(Is getting renovated at the moment) - Dating back to 1913, the legendary Clärchens Ballhaus is a proudly old-fashioned kind of place. Originally catering to ordinary working-class Berliners, Clärchens is the last proper dance hall in Berlin, and welcomes people from across the world. Cross the front terrace (the house originally here was bombed) and enter the hall that hasn't changed much since it opened. On the menu there's excellent pizza and German comfort food. After dinner, there's dancing: salsa on Monday, tango on Tuesday, swing on Wednesday, chacha and waltz on Thursday and Sunday afternoon, and a raucous live band on Friday and Saturday. Recommended.
