Green Door

There’s a sign outside, but the door—green, obviously—is locked. Ringing the doorbell activates a light in the bar, and if any one of the staff sees it, they might come and let you in. But don’t let the uncertainty put you off: once you’ve passed the admittance test, you’re free to enjoy some of Berlin’s most skillfully mixed cocktails in one of the most stylish rooms in town. While the menu offers a few house specialties and clever twists, the focus is primarily on 20th-century classics, prepared with high quality ingredients. Much of the interior is taken up by the long, dark wood bar—there are a few stools against the undulating side wall and only a handful of actual tables—but the mood is relaxed and the crowd is unpretentious.
