Ralf Rüller’s The Barn has roasted in Berlin since 2012, supplying ten Berlin cafés with third-wave specialty coffee plus locations in Palma, Seoul and Dubai.
The outpost on Alte Potsdamer Straße sits north of the Sony Center, with outdoor seating beside the entrance. The pick: the nut cake — not a filler, but a serious companion to the flat white. For anyone looking for coffee at Potsdamer Platz with outdoor tables, this is the better choice over the Sony-Center stop.
