The need

NJANSANG serves contemporary Cameroonian cooking. The chef wants a full dining room without spending her days on the phone. Some of her customers live abroad and would like to treat a relative back home.

For their customers

A customer reads the menu and rules out what they don’t eat: peanuts, gluten, chili. They book in two minutes without calling and get a confirmation. From Paris, they can order a gift box and have it delivered to their mother in Douala.

What I built

  • The restaurant menu with the Vegetarian and Peanut-free filters on, and the number of dishes left

    A menu you can filter

    Diet, allergens, spice level: you tick a box, the menu shrinks and shows how many dishes are left. A customer with an allergy quickly finds a meal.

  • First step of the booking: a choice between a regular table and the chef’s table, then the number of guests

    A booking in 5 steps

    Table, date, time slot, contact details, summary. A full slot offers the waiting list, and the confirmation can be added to the calendar.

  • The Takeaway page, with its gift boxes and dishes to order

    An order sent by WhatsApp

    The customer builds their order and chooses pickup or delivery, including for a relative. The summary goes to WhatsApp, ready to read.

Design choices

A menu printed on cream paper, with the warmth of terracotta and ochre. A few sections switch to a night background, like a dining room lit by candles.
