In the grand tradition of upscale clubs, Bar Tausend is well-hidden behind a steel door under the Friedrichstrasse S-bahn tracks and guarded by a discerning doorman. The futuristic main bar area, basically a long tunnel with circular lights at either end and mirrors above, looks like something out of the classic German film Metropolis. It would feel a bit claustrophobic if not for the excellent cocktails and stylish clientele. Hidden behind the bar is an even harder-to-get-into restaurant, whispered about by Berlin foodies—the so-called Tausend Cantina. For an unforgettable meal, call for in advance for reservations.
