About Au Bureau

“Au Bureau” is a restaurant chain inspired by the British pubs, a subsidiary of Groupe Bertrand, the French-owned biggest restaurant group, founded in 1989.

Targeting B2C customers through HTML5 mobile games

Au Bureau is always innovative with their marketing campaigns and is never afraid of testing unconventional marketing materials to bring in more customers to their pubs/restaurants.
