Kurfürstenstraße 58
It might be a little hard to find, but well worth the effort. First you need to go to Cafe Einstein, and then just before entering the dining room, notice what appears to be a service stairway to your left. This will lead you upstairs to the bar.
The bar has a wonderful old-school charm, and a soft dark mood. The perfect atmosphere for enjoying an expertly crafted Old Fashioned. Originally, the bar was just the one room in which it occupies, but they have been expanding the sitting area by taking over some of the surrounding rooms on the floor. Many of them include display cases with an almost museum-like display of many of the antique, and/or obscure spirits which they have acquired.
