Francophiles rejoice! Mastan is not one to be forgotten. The interior is giving "fine French restaurant", very white tablecloths with a lot of beautiful wood around, executed with attention to detail, as is the service. The menu is a la carte with a focus on classical, French meat dishes and a lot of offal. They are serving some amazing terrines, tartare, black pudding and guinea fowl. You don’t really see this kind of French cooking in Berlin, using such good produce and keeping it real in a classy but still not-too-fancy setting. Definetely worth a visit.
Do not jump straight to the mains, the appetizers are the stars of the show.
