This is Istanbul's biggest and best underground electronic music club, with the capacity for up to 600 people. Big-name international DJs from Germany, the US, and the UK join local talent behind the decks, which are set up in the center of the room to allow the audience to feel more connected to the artists. House, techno, electro, and dubstep all get played here on an impressive Funktion-One sound system. There are also sometime live visual artists working in different mediums to create a full audio-visual experience. There's no point getting here before midnight, as parties go until 5 or 6am. On weekend nights, after-parties sometimes keep going until 10am for the truly hardcore. Like most of Istanbul's best nightlife, it can be found on a lively side-street of Istiklal Caddesi. There's a smoking area on the balcony, which is a great place to watch the never-ending throngs of late night party animals come and go from the surrounding bars.  Tickets can be bought online or at the door.
