Nakau Higashi-Ginza is a Japanese chain restaurant in Ginza serving gyudon, oyakodon, and udon. The oyakodon comes with soft egg and chicken over a large portion of rice, and curry and karaage can also be ordered. It opens early in the morning, and orders are placed at a ticket vending machine and paid for with Suica. During lunch hours, customers crowd in and food takes a long time to come out.
