The setting at 3 Bis is charming and super-casual - the unfinished-plywood walls and bar are covered with marker-drawn messages from past customers, and the upstairs dining room is reached via a narrow exterior ladder-like stairway. With only two seats at the ground-floor bar (plus standing room for maybe half a dozen more) it's not an all-night destination, but it is a fun spot to drop in for a quick glass of sake or two before or after dinner.

You can choose from two dozen sake by the glass, among them many limited-time seasonal specials, and there are pre-selected three-part tasting flights. The small food menu is mostly simple sake-friendly fare like stuffed mushrooms, smoked duck and Japanese pickles, plus several items available for delivery from a nearby French delicatessen, including a nice smoked-salmon mousse. Most food items are priced Y300-500, while sake is typically Y600-900 per glass or Y1000 for a tasting flight.
