This French-style establishment is where the cool and slightly alternative crowd of District 4 loves to hang out, and so do we. Wooden tables, a concrete wall and industrial lamps set the tone and the coffee we had was solid. The croissant stuffed with scrambled eggs and bacon energised us for the rest of our Saturday, the service was friendly and getting all of the little extras we asked for wasn't a problem. Bonheur also has a pleasant outdoor seating area on Bullingerplatz next to the fountain and serves lunch and dinner with a French twist. A good alternative to the city centre's hipster cafés.
