What needed solving.
The background
Chez Mounier is a family-run bouchon (a traditional Lyon eatery) on rue des Marronniers, in Lyon's 2nd arrondissement, open since 1985 and run across three generations. Everything is made in-house: quenelles, tablier de sapeur, salade lyonnaise.
The constraint
The bouchon is a codified genre, and its customers are wary of anything new. A site that was too modern would have rung false — and cast doubt on the authenticity of the cooking. The site had to be current in its technology and timeless in its appearance.
The response
Authenticity is proven through detail: the menu states what is homemade, dish by dish; the “about” page tells the story of three generations with dates; and booking stays by phone because that is how this restaurant works. You do not impose a form on a place that answers the phone.
The scores recorded at delivery.
Lighthouse scores for the live site. We publish them as they are: when one is low, its cause and the plan to fix it are set out below rather than glossed over.
Every design choice, and the reason for it.
Gingham tablecloth, without pastiche
Deep red, off-white, a discreet pattern in section backgrounds. The codes of the bouchon are referenced, never literally imitated — pastiche shows, and it backfires.
Homemade, dish by dish
Each dish carries the label when it is prepared on site. It is the bouchon's central argument against establishments that simply reheat, and it had to be verifiable line by line.
The phone as the main action
The call button comes first, permanently on mobile. Adding an online booking module would have created a channel the restaurant does not check — the worst possible scenario for a customer.

Static site, free hosting
No application server, no database. The annual running cost is that of the domain name.
A typed menu
Dishes, prices and the “homemade” label in a data file. The seasonal update does not require touching the HTML.
How the site makes itself findable.
“Bouchon lyonnais rue des Marronniers”
Rue des Marronniers is a destination in its own right. Targeting the street rather than the city captures an intention to choose right now, within a two-hundred-metre radius.
Specialities indexed
“Quenelle maison Lyon” (homemade quenelle), “tablier de sapeur”: each speciality is named in structured content. These are searches made by tourists planning their meal.
Usable by everyone.
Since June 2025, the European Accessibility Act has required digital accessibility from a large share of online services. We build it in at the design stage rather than retrofitting it.
100/100 despite a textured background
The background pattern is toned down enough for all text to keep 4.5:1. A decorative pattern should never cost a single point of contrast.
