So, Café Select’s back room — formerly accessible only to the select few via the kitchen — now has a sexy separate entry via a sidewalk grate and a long utility tunnel. It’s open on Thursdays, Fridays, and Saturdays, and after one night in business, we’ve already heard a Beatrice regular refer to it as “the new Beatrice.” We’ll resist that comparison — first, because look what happened after we went there with Chloe. And second, because the place is tiny. In fact, it feels something like a duplex studio with a damn good sound system. Plaster chips on the wall, webs of Christmas lights, a caged Edison bulb, and a U.S. Army “No Trespassing” sign give the low-ceilinged downstairs a gritty bunker vibe. A giant disco ball hangs over the stairs and the treehouselike upstairs loft is dotted, à la Heathers, with art-class stools. Last night the door wasn’t guarded, but expect that to change given the limited capacity.
