Nanoan is a restaurant in Tennoji and Abeno, Osaka, serving vegetable-centered Japanese home cooking with sake accompaniments. Its signature dish is the ichiju hassai lunch, which pairs rice and soup with one main and seven small side dishes. The restaurant occupies a restored wooden house built in the Taisho era and over 100 years old, where guests remove their shoes and sit at low tables or regular tables. Lunch starts at 11:30 a.m. and is limited to 50 meals a day, so phone reservations are needed in advance.
