I was wary of this restaurant from the other reviews, but it proved to be a good bet. Portions were generous , and staff were warm and friendly (not so often does that happen in this city). It's nice having an oasis of Britishness in Berlin's coolest district. Amazingly easy to reach too, with Mehringdamm U-Bahn just outside the door.
The outdoor seating to the side is a real suntrap and a nice place to get some rays on one of Berlin's rare sunny days.
