Overview

Ordering at a fine restaurant, without the waiting or the pressure

La Lumière is a concept app designed for a high-end French restaurant. It lets guests look through the menu, book a table and pre-order their food in advance, so the moment they sit down, the experience is about the company and the meal, not the logistics.

The target users are middle-aged and older, high-earning and well-educated people who are short on time. Many of them also experience age-related limitations such as hearing loss, which makes ordering in a loud, hectic restaurant stressful and dependent on help from others.

A set requirement of the brief was that the app had to include a group of people with impairments, so accessibility was a constraint from the very start, not something added at the end.

Over five months I led the project end to end (user research, wireframing, prototyping, interaction and visual design, UX writing, and two rounds of usability testing), taking the concept from problem framing to a high-fidelity, accessible prototype.

The result is an app that preserves the comfort and atmosphere of a luxury dining experience while quietly removing its friction: no phone call to reserve, no waiting for the menu, and no pressure to decide on the spot.

The problem

Less time, more pressure

Career-driven people have less time to spend waiting in a restaurant for their food. On top of that, with increasing age many guests rely more on help from others: hearing impairments, made worse by loud and hectic environments, turn a simple order into a stressful exchange.

The goal

Order ahead, stay independent

Let users order their food in advance, at their own pace, saving time and ensuring their independence even with age-related limitations. The visit becomes about enjoyment, not navigating a process that works against them.

My Role

Led the project end to end

Over five months I owned La Lumière from problem framing to a high-fidelity, accessible prototype: research, design and two rounds of usability testing.

  • User research & interviews
  • Personas & user journey mapping
  • Wireframing & prototyping
  • Interaction & visual design
  • UX writing & usability testing
Tools

What I designed with

I worked mainly in Figma, from wireframes to the high-fidelity prototype, with a few supporting tools for research, content and visuals along the way.

Research

Understanding who eats here, and why it's hard

During user research, two groups stood out. The first were around sixty years old: well-educated, established in leadership roles, and high-earning. The second were in their late thirties, building their careers, earning well, and frequently holding business lunches at expensive restaurants.

Because there are demographically more older people, and because wealth, and therefore high-end restaurant visits, tends to increase with age, I chose to focus on the first group. They also surfaced the most acute, under-served needs: time pressure compounded by age-related hearing loss.

01
Limited time
A full schedule of appointments leaves users with little time for work or family, and even less to spend waiting in a restaurant.
02
Long waiting time
Waiting a long time for food is frustrating and time-consuming, especially during busy hours.
03
Hearing impairments
Users with limited hearing struggle to understand the waiter, which makes communication challenging and the visit dependent on help.
04
Pressure when ordering
Users feel stressed about making quick decisions on what to eat and ordering on the spot.
Competitive Audit Work in progress

How others handle the menu and ordering

Finding direct competitors was hard: almost no high-end restaurant offered a menu-and-payment app, so beyond one close match, Tao Downtown, I deliberately added two larger indirect players, Domino's and McDonald's. They don't compete in fine dining, but their ordering and payment flows are mature and widely used, which made them useful references for how to present a menu, handle checkout and approach accessibility. I compared all three across first impressions, interaction, visual design and content.

Accessibility was the weakest area for every competitor: tiny fonts, no screen-reader support and limited languages, exactly the friction my older, hearing-impaired users feel most. Not one offered a calm way to browse and pre-order before arriving at a fine-dining table.

That gap, together with how much a strong visual identity and appealing food photography helped the best performers, pointed La Lumière's direction: legible and accessible, with a confident look and an order-ahead flow that removes pressure rather than adding it.

Persona

Designing for Alice

Alice is an older editor of a food magazine who needs an app for a restaurant where she can look through the menu and order her food in advance, because she feels rushed to make a quick decision and has trouble hearing the waiters.

New Jersey, NY

"I want to maintain my independence and be able to focus only on the people and things I love."

Goals
  • Spend quality time with her beloved niece
  • Enjoy quality food in a high-end restaurant and broaden her horizon
  • Preserve her independence by placing her own order, in advance
Frustrations
  • Hard to understand the waiters acoustically over background noise
  • Worsening hearing makes ordering stressful
  • Feels rushed, wishes she had more time to decide on a menu

Alice is a 60-year-old food-magazine editor living alone in New Jersey. Since the sudden death of her husband, she spends her weekends with her niece, with whom she shares a love of food. Over the past year her hearing has worsened, making it hard to understand the waiter, and as a fiercely independent person, she's uncomfortable relying on help. She wishes she could browse the menu and order in an app before arriving, so that once she's at the restaurant the food simply comes and she can enjoy the meal without communication troubles.

Secondary persona

James could use it too

I designed the app around Alice, but a second persona, James, shows a younger guest it could serve just as well: an ambitious lawyer who wants to pre-order and pick up his meal without losing his whole lunch break.

"I want to exclusively focus on my career, while not lowering my standard of living in the meantime."

Goals
  • Focus on his career and make partner within a year
  • Order his food in advance so he only needs to pick it up at lunch
  • Keep a good standard of living
Frustrations
  • Waiting for food eats up most of his lunch break
  • No time for the fancy restaurant next door with colleagues
  • Won't settle for fast food either

James is a 38-year-old ambitious attorney at a major law firm in Philadelphia. He has worked there for eight years and is on the brink of making partner. With another colleague in the running, he often uses his lunchtime to prepare for upcoming meetings, so instead of joining coworkers at the expensive restaurant next door he picks up food from a nearby eatery and eats at his office. It costs him a lot of time, which frustrates him, yet the small fast-food joints aren't an option for him either.

User Journey

Alice's journey today

Alice's goal is to spend a nice evening at the restaurant without having to rely on anyone for help during the ordering process. Mapping her current visit revealed emotional ups and downs, from finding the restaurant's number and the difficult phone reservation, to the long wait and the pressure to choose quickly.

Information Architecture

A structure built around one confident path

Everything centres on the home screen, where the two primary actions, Book a Table and Menu, sit side by side. From booking, the guest moves through a single guided flow that folds the pre-order and payment into the reservation itself.

User Flow

From home screen to confirmed pre-order

I aimed to keep the flow simple and intuitive, even for first-time pre-order users, since most people have never ordered their restaurant meal in advance before.

01
Browse the menu
From the home screen, the guest opens the menu to see dishes, prices and photos, then returns home to start a booking.
02
Book a table
Choose the party size and pick a date and time from a calendar that shows availability at a glance.
03
Pre-order food
Opt to pre-order, then place the food order directly, with dish images to support the decision.
04
Contact & payment
Enter contact details and credit-card information to complete the booking and the pre-order together.
05
Review & pay
Review an order summary before paying, a deliberate checkpoint so nothing is committed by surprise.
06
Confirmation
Receive a confirmation showing the reserved table and the pre-ordered dishes, with an option to add it to the calendar.
Paper Wireframes

Sketching toward something minimal

My goal was a minimalist yet elegant design that focuses only on the essentials, easy to use for target users who are around sixty and not digital natives. I sketched several versions of the same screen, then drew a refined version pulling together the strongest ideas.

Digital Wireframes

From “La Maison” to “La Lumière”

The first digital version was clean and elegant with only the necessary elements: a menu button, a photo of Provence, the restaurant name, a short intro and three blog posts. After the first usability study I renamed it “La Lumière”, added a clear Book a Table button beside Menu, and wrote a blog post explaining the pre-order process, since so few users had done it before.

First version: “La Maison”
A single menu button on the main page. Functional, but the reservation, the whole point of the app, was buried, and the pre-order concept wasn't explained anywhere.

Prototype

From low to high fidelity

I built a low-fidelity prototype to test the core flow end to end: homepage → menu → book a table → choose date and time → pre-order food → enter card details → review summary → pay → confirmation. After two rounds of testing, I rebuilt it as a high-fidelity prototype with the full visual design and real content.

Research Plan

Planning the usability study

Before testing, I wrote a study plan to keep the sessions focused. The goals: find out whether people understand how to pre-order, whether the app is difficult to use, whether hearing-impaired guests need assistive support, and whether there's real demand for pre-ordering in high-end dining.

Method
Unmoderated usability study + online survey
Setting
Remote, Switzerland: each participant at home
Sessions
10–11 Nov 2023 · 5–10 min each
Participants

The script

The tasks I asked participants to complete:

Open the menu and notice the dish you like most. You'll need it later in the ordering process.
What do you think of the visual appearance of the menu? Anything you'd change?
Go back to the home screen.
Book a table for 12 November at 11am, then press Confirm and Pre-order.
How easy or difficult was it to book a table? Anything you'd change about the process?
Choose the meal you liked most on the menu and confirm.
How easy or difficult was it to choose the food? Anything you'd change?
Insert your credit-card information and check out.
How easy or difficult was checkout? Anything you'd change, or other payment options you'd want?
How did you feel about the menu and payment app overall?
What did you like and dislike about it?
Would the whole journey be easy or difficult without any instructions?
What would be a way to improve it?

Afterwards, each participant completed the System Usability Scale, rating ten statements (such as “I think the app is easy to use” and “The main user flow is clear”) from strongly disagree to strongly agree.

Usability Testing

Two rounds, five participants each

I ran unmoderated usability studies with five participants (two men, three women), asking them to complete tasks in the prototype. The first round tested the low-fidelity flow; the second tested the refined mockups after the initial changes were made.

Each finding came from watching multiple participants hesitate at the same point for the same reason, which made the necessary changes unambiguous. The biggest themes were date clarity, the discoverability of booking, and reassurance at the moment of decision and confirmation.

"I'd actually use this. I never knew you could order before you even arrive."
Affinity Mapping

Clustering what we saw on a sticky-note board

After the sessions I put every observation and quote on a virtual sticky-note board and grouped them into themes. The clusters that came up again and again became the findings I acted on.

User Flow / Accessibility
“I'm sure I'd always find my way through the app without guidance”
“It's very intuitive, I had no problem finding anything”
“The font really suits a high-end restaurant, and so do the colours”
“I didn't find anything confusing, so I wouldn't change any terms”
Payment
“It was really easy to check out, with a nice summary for a good overview”
One user liked that the payment summary looks like a restaurant receipt
One user found the confirmation button easy to find
“The payment page works like ones I knew, so it felt fine”
Preorder
“The food ordering process was really easy”
“The pre-order page is well structured and easy to read”
“The only way to improve the app is to put some pictures on the menu”
One user found it especially good for hearing-impaired guests, who can pre-order ahead
Book a table
“The calendar was very nice and exactly what I'd expect”
“The ‘Book a table’ button is centre screen, really easy to find”
“It shows the available times as pills, very nice for navigation”
“It was very smooth to book, with a nice summary of my selection”
Menu
“I can easily find the menu”
“The buttons were really clear and easy to find”
One user had no problem closing the menu and going back
One user felt the home page suits someone who just wants to book
Before / After

How testing reshaped the screens

A calendar with dates and weekdays
Many participants struggled to book because they didn't know which day of the week October 12 was. I added a calendar showing both the date and the weekday, making it far easier to find the desired date.
BeforeBefore: date selection with weekday buttons only
After
After: full calendar with dates and weekdays
“Book a Table” moved to the home screen
The button was originally on the menu page, which many participants found confusing. I moved it to the home screen next to the menu button, so the most important action is the first thing they see.
BeforeBefore: Book a table button on the menu page
After
After: Book a table on the home screen
A confirmation that reassures
Participants wanted to see the ordered menu on the confirmation page, so I added it to reassure them they'd ordered correctly, along with an “Add to calendar” button and a “Maybe later” option.
BeforeBefore: sparse order confirmation
After
After: confirmation with order details and add-to-calendar
Photos in the pre-order menu
Participants said they'd appreciate images on the pre-order screen, so I added photos of the dishes to make the menu more intuitive and to support decision-making.
BeforeBefore: text-only pre-order list
After
After: pre-order menu with dish photos
Iteration

Small changes, big difference in confidence

The pattern across both rounds was consistent: the flow worked, but users hesitated wherever the app asked them to commit without enough context. Every iteration aimed to replace that hesitation with confidence: surfacing the primary action, clarifying dates, and adding reassurance at the points of decision and confirmation.

Because pre-ordering is unfamiliar to most people, much of the work was about gently teaching the concept as users moved through it (with a dedicated blog post, dish photos, and a clear summary step) rather than assuming they already understood it.

Design

Quiet luxury, in a French key

The visual language is designed to feel like the restaurant itself: refined, warm and unhurried. A deep Bordeaux red anchors the key actions against a cream-and-white base, and an elegant serif gives the brand a sense of occasion without tipping into ornament.

Restraint was the point. For users who aren't digital natives, every screen shows only what's needed for the step they're on: generous spacing, large legible type, and one clear action at a time.

The brand wordmark, La Lumière, I designed specifically for the app: an elegant serif logotype that sets the tone the moment it opens. The same logo also features in my graphic-design work.

Accessibility

Designed so no one has to ask for help

Accessibility wasn't a layer added at the end: it was the reason the app exists. Three considerations shaped the experience for users with hearing and vision limitations, and for those who aren't digital natives.

01
Order without verbal communication
A pre-order function lets users with hearing impairments, including deaf guests, order their food online, with no need for verbal communication.
02
A guided, signposted flow
Icons show which step of the ordering process the user is on, making the flow easy to follow for people who aren't digital natives, and for guests who don't speak the language as a mother tongue or don't read it fluently.
03
High-contrast, readable text
High-contrast colours and backgrounds ensure that people with vision impairments can read the text easily.

What's next

Where La Lumière could go

01
Soft launch
Release the app to gauge real interest and fix anything that isn't working, guaranteeing optimal experience and functionality before scaling.
02
Build awareness
Invite gastronomy journals and food bloggers to test the app in the restaurant and write about it, establishing a stronger presence in the public sphere.
03
Expand to a B2B model
Reach out to other high-end restaurants about integrating the app, positioning it globally and pushing the industry toward a more digital, future-oriented direction.
Outcome

A new way to dine, without losing the experience

La Lumière changes the way we order at a restaurant without sacrificing the comfort and atmosphere of a luxurious dining experience. It lets guests conveniently pre-order their meals from home: no calling ahead, no long wait for food, and no pressure to decide on the spot.

Time saved
Ordering ahead removes the wait: the meal is ready, and the visit is about the food and the company.
Independence preserved
Guests with hearing limitations can order entirely on their own, without relying on anyone's help.
Atmosphere intact
The luxury experience stays: the app simply removes the friction around it.
Strengths Work in progress

What I'm especially good at

Across this project, these were the activities I felt most confident in and enjoyed the most, the parts of the process where I could really push the work forward, from early research and structure to interaction, branding, writing and the moments of invention in between.

  1. PersonasTurning research into believable, decision-ready personas that keep the team designing for real people.
  2. User flowsMapping the path from entry point to goal, so every screen has a clear purpose and place in the journey.
  3. WireframingSketching fast on paper and refining into digital wireframes, exploring many layouts before committing to find the simplest structure early.
  4. Interaction designConnecting the wireframes into a working prototype and crafting the transitions that make a flow feel effortless.
  5. Branding & visual identityPutting together a refined colour concept and building a strong brand, from the logo to the full visual identity, that fits the restaurant.
  6. Usability studiesPlanning and running the sessions end to end, from writing the test script and tasks to moderating and synthesising.
  7. UX writingMicrocopy, labels and in-flow guidance that explain unfamiliar ideas without adding noise.
  8. Writing & storytellingShaping the narrative of a project so the thinking behind each decision comes across clearly.
  9. Inventing innovationsSpotting gaps others overlook and turning them into original, useful concepts, like pre-ordering in fine dining.
Reflection

What I learned

An untapped concept

  • Pre-ordering has room to grow: although some pre-ordering systems exist, there are no standardised solutions yet, and in my market analysis it was mostly limited to the fast-food sector.
  • Demand is there: most usability participants weren't familiar with pre-ordering, but said they'd love to use such an app or service once they understood it.
  • An unexpected fit for deaf and non-speaking guests: because the whole order happens in the app, deaf or mute guests can order their food effortlessly, and still enjoy eating in the restaurant in person.

Design takeaways

  • Teach unfamiliar concepts in-flow: when an idea is new to users, the design has to explain it as they go, not assume prior knowledge.
  • Accessibility drives clarity: designing for hearing and vision limitations led to a simpler, calmer product for everyone.
  • Test, then trust the pattern: the clearest changes came from watching several users stumble at the exact same spot.
  • Mind the safe area: headlines and logos in the top bar have to stay clear of the camera cutout so it doesn't crop them, and since different phones place the camera differently, I designed for a current, common device.
