In the location's words:

You have to look a little closer to find the Zwoeinz in the small but indispensable Hochstadenstraße in the KWARTIER LATÄNG, the hourly nightlife district.
A few steps separate us from the outside world and form the gateway to our alternative living room for the Veedel and the whole city. We like it a bit dim here, sometimes too loud, but always personal. Nothing pleases us as much as when we see our guests again. Preferably on a regular basis.
We attach a lot of importance to good music here. That must never be missing.
There aredrinks, too, of course. But we prefer to be guided by quality and personal taste rather than by big brands or low prices. We stand for variety. Not only with cocktails, long drinks and shots. No, also with gin, absinthe and much more. The view from one of the coveted counter seats to the bulging spirits shelf behind the bar has already produced many a new favorite drink.
