not exactly haute cuisine but in my opinion and that of any berliner ive spoken to this currywurst station in mehringdamm is probably the best in all Berlin. I pretty much head there for the post beer supper every night when im over . About 4 euro should see you adequately fed and watered if fast foods all your looking for. The Clash is just accross the road and stays open till quite late . Which is handy as what tends to happen is you go to the curry stand after your supposed last beer , but the hot food has a tendency to start you off again in the mood for another few . Order the hot onions with care though because Ring of Fire will certainly be something youll consider humming in the morning if you do.
