Manhattan – Flatiron District
201 E 24th St at Third Ave
Reserving a private "Polar Cave" at this swanky new Arctic nightclub in Gramercy Park's Marcel Hotel may run you $350, but if you're in the mood to drink your $17 cocktails in total seclusion, it's worth every penny. Decorated with faux-fur pillows, dripping chandeliers, white leather couches, huge ottomans, silver brick walls and tea lights galore, this subterranean hideout is the latest to hit Manhattan, following in the tradition of SubMercer. Overseeing the joint? David Bowd, who also ran the Royalton NY and the Mondrian LA.
