Mustafas Gemüse Döner
If you’re going to Berlin and for some reason can only eat one thing then this side of the road vendor is absolutely that one thing. The roasted vegetable kebab with halloumi cost under 5€ and offered more bang than I think I’ve ever seen for your buck.
These have popped up all over Berlin, including one a short walk from Museum Islan don Neue Promenade which even has seating but the pricing and the portion sizings do differ.
