Eureka! is a modern izakaya restaurant in Nishiazabu, Tokyo, specialising in pairings with Japanese sake. It serves sake from breweries across the country alongside creative dishes from a French-trained chef, and staff select drinks to match the food. Staff fluent in English explain the subtle differences between sakes, suggesting everything from draft sake to local brewery sake and warm sake served at precise temperatures. Portions of food are small, and sake is priced high relative to the amount in the glass.
