Ralf Rüller’s The Barn has supplied ten Berlin cafés with third-wave specialty coffee since 2012, plus locations in Palma, Seoul and Dubai.

The flagship store on Ku’damm sits in the historic Café Kranzler building — the red-and-white awnings remain, single-origin coffee from in-house roasts inside. The pick: a filter coffee with the orange cake from the in-house patisserie. Prices play the Ku’damm game — for Berlin-roasted specialty coffee in the postcard setting, this is where to start.
