This seems to a more tourist-friendly branch of Yaesu's legendary Codename Mixology bar, known for their amazingly inventive cocktail creations. It might be hard to imagine a blue-cheese martini or a "breakfast" cocktail that tastes like eggs and bacon, or a Thai-soup-inspired Tom Yum Cooler, but somehow they all taste fantastic.
This branch has a ten-seat counter in the main bar area, and a few booths and tables in back for groups. The decor is plush, and the overall atmosphere is relaxed and somewhat subdued. Cocktails average around Y1500-1800, and the cover charge is around Y1000. There's also a small food menu, more or less designed to go with the drinks here.
