Udon Tamatama Japanese noodle is located in the middle of Dotonbori in Osaka. Its signature dish is cold bukkake udon, served with tempura shrimp and chicken karaage. Customers take a numbered ticket from a kiosk before ordering. The noodles are boiled for about seven minutes, chilled in ice, and reheated before serving, and the narrow restaurant has around 12 to 15 counter seats.
