Ohitotsuzen Tanbo

The speciality here is the least glamorous part of the meal – the rice, which comes from an organic farm the restaurant manages in Niigata Prefecture. It's served as ochazuke, a classic comfort food of rice topped with meat or fish, over which hot tea is poured. English instructions explain how to eat it. It's walkable from the south side of Shinjuku, with white door curtains out front.
