On Saturday night, Matt Kliegman, Carlos Quirarte, and Taavo Somer—the men behind such downtown hot spots as The Smile, the Jane, and Freemans—put on a Halloween party in an abandoned building on 28th Street that promised "13 floors of vacant goodness." The space was indeed bare-bones: Picture oil drums, Porta Potties, holes in the wall, a tricky winding staircase, industrial equipment, and plenty of dust and rubble. The background served to throw the costumes into high relief: Kirsten Dunst showed up as Jodie Foster in Taxi Driver; Rogan Gregory was Christ, complete with a crown of thorns; Michael Stipe's black clump of balloons represented oversized caviar; and Michelle Trachtenberg was a kinky Marie Antoinette. A thrifty one, too, apparently. "Do you know how much this wig costs? Like, $1,000," she said. "I just knicked it from costumes."
