Matsuya Tenjin is a 24-hour branch in Tenjin, Fukuoka, serving gyudon and other rice bowls. The menu includes gyudon, curry, and umatoma hamburg, with a choice of rice sizes. At the entrance kiosk, you take a number and pick up your food when it appears on the screen, then sit at an open seat inside and order on a tablet. The food is salty and sweet, which is heavy for anyone looking for mild flavors.
