A small, hole-in-the-wall shop in Tokyo Station's underground shopping complex, Daruma boasts a surprisingly large selection of hard-to-find premium sake - 80 kinds in all - including multiple varieties from popular breweries like Kubota and Denshu. There's good sashimi as well as dishes like crab and horsemeat shabu-shabu. Budget around Y3500 at dinnertime.
