Billing itself as a "hedonistic nightclub," the Ivy Hotel's Envy is a sleek, sexy four-level space that caters to the fashionable club-goer. It's furnished with couches that double as beds, evocative wall hangings, and a cadre of erotically attired professional dancers that get the crowd out on the dance floor. It's a voyeuristic sort of place – lots of cleavage and booty shaking. If the action inside gets a bit too steamy, check out rooftop bar Eden, a tropical paradise of potted palms, cozy wicker furniture and fabulous skyline views. And a pool.
