About 50 years of “Legendary” Rice Bowl

Received top prize at 22nd food service industry award for product development department.


In 1971, Sutadonya was founded, and its owner had the vision of offering filling meals at affordable price for the young generation.
Through trial and error, what started as a back-kitchen meal for the staff evolved into the “sutadon.”
With the kick of garlic-enhanced soy sauce and a standard portion that is 3 rice bowls’ worth of food, the dish quickly became a hit among our best customers and eventually made its way onto the regular menu.
The “sutadon” became beloved of nearby university students and office workers, not to mention hungry local youths.
Thus, the “Meibutsu sutadon no mise” was spun off as its own store dedicated to serving this dish.
