Ittaikan is a Japanese curry restaurant in Ginza, Tokyo, that serves curry over rice cooked in a pot. It fills freshly cooked rice with spicy meat curry, and diners choose toppings such as fried shrimp, eggplant, and egg. The restaurant opens at 8 a.m., and after ordering, cooking the rice and serving the food takes about 30 minutes. Waits can stretch to about an hour, and the small space makes the line long.
