Sketch serves late, but more important, Sketch really comes alive late at night -- when restaurant crews, homeward-bound Creekers, the hammered, the shattered, those whose nights are coming to an end and those whose nights are just getting started all seem to converge on the subterranean wine bar. The by-the-glass list and super-call booze (the Del Maguey Pechuga mezcal at $14 a shot is worth every goddamn penny) might be the hook that gets us in the door, but Sketch's well-conceived menu -- and, in particular, the derivative, completely addictive beef carpaccio "Harry's Bar" -- is what keeps us coming back night after night after night.
