Arakicho 6-42, AG Bldg 2F. Open 7pm-midnight. Closed Sundays.
This tiny second-floor bar has a Buddhist theme - the name in Japanese is "bouzu", or Buddhist priest - with a little shrine in one corner and bartenders dressed in appropriate priestly garb. Drinks include several variations on shochu and plum wine, and there's a small food menu to go with your drinks.
