Jazz and funk, cocktails and low-level lighting: a good mix if you are looking for a place to unwind with a special someone. In fact, you might want to amble through the narrow, boxcar-like space toward the outdoor garden. There, you can down a few creative cocktails made from the likes of champagne and sake. The after-work crowd here tends toward the professional side. Happy hour lasts until 10pm during the week and until 8pm on weekends. TRAIN: L to 1st Ave; 6 to Astor Pl
