A very close friend of mine owns this bar. It looks tiny from the outside, but it has two rooms you have to pass until you get to last one which is a discofloor. I play music there from time to time and I am always surrounded by nice people und friends.
The best cheeseburger in Berlin costs less than 5. Burgermeister is mandatory in town when you're craving for a basic and delicious to the bits chesseburger.
A very good reason to travel West: the C/O, next to the formerly infamous Berliner Zoo tube station, is an awesome museum dedicated to photography and visual media. Previous exhibitions include Larry Clark, Martin Parr, Anton Corbijn, Annie Leibovitz and Stephen Shore.
