7. Cielo, New York
DJs from New York icon François K, who throws Monday night's Deep Space party, to major U.K. and Ibiza stars make this longtime NYC spot an underground temple. The no-frills club also has a reputation for booking new talent just before they get too famous to play somewhere this small. Much of the credit goes to owner Nicolas Matar, who honed his skills during an eight-year residency at Pacha in Ibiza. "Nicolas is a DJ, too, so he knows how to keep us happy," says DJ Harvey. "Custom-built club with lovely custom sound."
Fun Fact: Matar's parents were regulars at Studio 54, the legendary Seventies disco club, and he learned how to DJ by listening to his father's vinyl collection.
