Since the Ibiza institution with the double-cherry logo opened its first North American branch in 2005, it's grown into perhaps the city's biggest superstar-DJ magnet. Danny Tenaglia, Benny Benassi, Erick Morillo and more spin for unhinged late-night parties that stretch well into the next morning. The four-level club's main room features an LED-covered DJ booth and a Dynacord speaker system with 17 subwoofers for maximum thump, but regulars know the coziest spots are upstairs – Pachita is a penthouse luxury lounge, and the second-floor Atrium has balcony views. "I love to go a little dark and dirty sometimes," says Steve Angello, "so I love this place."
