Frank Hearts Berlin
The title sounds pretty negative in German, but this is actually a place of light hearted fun. Located in Kreuzberg near the river in a backyard of Köpenicker Straße it is one more urban and rough paradise of Berlin club culture. It's inside an old industrial building and therefore brings the typical charm of Berlin underground clubs mixed with a few fun interior details. They only open every once in a while for special parties, so they don't have a regular club program. But if you do come across the promotion of one of their events do check it out as it will be in a lovely atmosphere with an interesting crowd.
