Clärchens, in the Berlin-Mitte district, is a 100 year old former ballroom, complete with a vintage mirrored hall, where live music and dance is fueled by delicious Italian and German foods and, of course, beer. On Monday and Wednesday nights you can attend free dance lessons (Salsa and Swing respectively) and pick up some moves among the aged grandeur of this uniquely charming setting while meeting local Berliners in their twenties and eighties.
