Imadeya

Imadeya is a respected sake specialty store, but they carry more than that, including small batch shōchū (distilled alcohol usually made from sweet potatoes or barley), other made-in-Japan spirits (gin and whisky) and wines. Even better: there's a tasting counter (sake flights from ¥1500; wine flights from ¥2000; extra for premium selections; single glass options available). English menu and English-speaking staff.
