Bartender's choice: Constant, off-the-hook dance parties and the house specialty, the Ginger Rogers ($6). Experimental and deliciously noisy sounds, stiff drinks, and a chronic dance-party remix on the floor make Holocene a triple threat that brings the heat. A must-have signature cocktail, the Happy Finish ($6), is a tall order of bourbon and Chambord precisely blended with fresh measures of lime and cranberry. But if you're gonna be instigating a dance revolution, throw back the Pocari Sweat ($6.50), a combo of Hakutsuru sake, vodka, soda, sugar and salt (electrolytes!) mixed with a trio of lemon, lime and orange. That'll get the party started. HAPPY HOUR, DJs, LIVE MUSIC, SMOKING LOUNGE, QUEER NIGHTS, DRAG. (EB)
