If you want a beer at five in the morning, at ten in the morning or at two in the afternoon, Bei Schlawinchen is the only address you need. This classic neighbourhood kneipe—which never seems to close—has about six tables, a handful of stools and a perpetual cloud of cigarette smoke obscuring the satirical art and random artifacts hanging from the walls and ceiling. And while it can be almost impossible to get to the bar through the densely packed crowd at 3 a.m. on a Friday or Saturday morning, you can go in at any time of day and not have to worry about drinking alone. They have a few mixed drinks available, but don’t get any ideas: This is the sort of place you go to drink beer and lots of it, perhaps with a shot of Korn (grain spirit) to round out the night. A Berlin classic in its own way.
