G-Spa: Star Treatment

Think speakeasy meets day spa: Not even the paparazzi were clued in to the Feb. 2 opening of new Manhattan club G-Spa & Lounge. But stars like Lindsay Lohan, Eliza Dushku, Jay-Z, Kimberly Stewart and Jamie-Lynn Sigler knew to slip through the unmarked door off the lobby of Hotel Gansevoort in New York City's Meatpacking District down to the basement space. "I like it, it's low-key," said Lohan (who returned again the next night). Owned by Butter's Scott Sartiano and Richie Akiva, the nightspot—as small as some VIP rooms, with a 75-person capacity—features three lit whirlpools bubbling in the center of the room and a waitstaff wearing short robes and flip-flops. (By day the space will soon offer actual spa services.) Jay-Z held court with a posse until 2 a.m., and Sigler tiptoed across one Plexiglas-covered pool. Nothing like walking on water....
