Gravity

A giant gold-and-red brushed-metal fireplace makes the space pop, while projections resembling a psychedelic waterfall cover two walls. Flirtatious 20-something singles clamor for drinks at the long tile-backed bar and are treated to classic movies played on three flat-screen TVs hanging overhead. Opposite, a few roomy banquettes provide some of the only seating in the main room--but the action is on the packed dance floor, where DJs churn out hip-hop chart-toppers.
