Yoshinoya is a Japanese fast-food restaurant in Toyosu, Tokyo that serves gyudon, karaage, and unagi donburi. It sits directly in front of Toyosu Station Exit 4, and the menu ranges from basic gyudon to sets with karaage and abura soba. Each seat has a power outlet, and orders are placed on a touch panel with payment at the counter. At lunchtime a line of nearby office workers forms and you have to wait.
