Swinging, clinging, and dipping 21 stories above the asphalt can be a truly celestial experience, especially at the Starlight Room, which offers its dancers unparalleled visual proximity to the cosmos. As you and your partner head onto the dance floor, seduced by the Motown rhythms of the Starlight Orchestra, you'll realize that your terpsichorean backdrop won't be the plywood, concrete, and laser beams de rigueur at many a lesser hot spot; beckoning your booty instead is an expansive panorama of illuminated skyscrapers, glittering bridges, festively lit ferryboats, and the brilliant constellations that give the venue its name. The inside view's pretty nice, too: gilt-carved mirrors, silk draperies, a black marble bar, and elaborate florals that add to the whole ascendant atmosphere. The Starlight Orchestra performs Thursdays through Saturdays, 8 p.m. to midnight; DJs spin their stuff the rest of the week.
