A labyrinthine complex of half a dozen or so dancefloors accessed via the north-side entrance to Heinrich-Heine-Strasse U-Bahn station make up Sage Club, which caters to a relatively young, rock-oriented crowd. On Thursdays and Fridays it's a chilled-out, unpretentious place where skinny jeans and leather jackets tend to be the uniform of choice. On Saturdays you'll have better luck with some fetish gear, as Sage is the current home of the notoriously decadent mixed/straight sex and techno night, the KitKat Club (
