Directly underneath under the Warschauer Straße U-Bahn station DJs lay down tracks of R'n'B, straight house, soul, electro, disco and pop on seven dance floors within the vaults that date back to 1901. There's always a party here, 365 nights a year. Thursday is student night, Friday has party classics with free champagne before midnight for ladies, Saturday is Fruity Night, with juicy cocktails.
