High ceilings, great atmosphere, crazy hallway and bathroom. The food of course is amazing and even just ordering a cocktail at the handcrafted wooden bar is worth your while. In the evening it can get busy and loud yet it never feels crowded, and it's definitely an enjoyable ambiance.
If it is summer in Berlin, and you are looking for a place to have brunch - this is the place to be. The restaurant is located in a spacious and austere dining hall of a former hospital complex. The garden is very green, quiet and private.
