Butcher's Bar: a slaughterhouse speakeasy
Even though the 'Fleischerei' on Rosenthaler Platz serves up a pretty decent Currywurst, that's not why you're here, right?
Instead, you're planning to stride past all those sausage-munching diners and head straight for the London-style phone box at the back, which doesn't contain a telephone but does have a concealed buzzer.
And then it's just a case of ringing the bell, enduring the obligatory peephole assessment, then (hopefully) stepping through a steel door into the red-lit environs of Butcher's Bar, a speakeasy cocktail lounge hewn from a former abbatoir.
Tiled walls and meat-themed paintings attest to the bar's grisly past, but these days it's all about killer cocktails in a cut above the rest setting.
Order a 'Blood and Sand' to stay ironically on-theme, and try to avoid quips about getting alcoholically slaughtered.
*Update: the Butcher's Bar has now closed. Why not check out a '20s style burlesque bar instead?*
Butcher's Bar, Torstraße 116, 10119 Berlin, located in the 'Fleischerei' wurst and burger restaurant.
Head towards the toilets at the back, then turn left to find the phone booth entrance.
Opening times: Tues-Sat from 8.30pm
