In the location's words:

Bar Tausend has been an institution of Berlin's nightlife for over ten years. The timeless bar classic is hidden behind an inconspicuous steel door directly under the Friedrichtstrasse S-Bahn station. Bar Tausend is a unique, stylish oasis in the middle of the city center. High-quality drinks are served by the team of bar chef Pablo Enrique Muñoz Hoffmann.
