A service that allows you to change the "rice (normal)" of each set meal menu, including the morning set meal, to "yudofu" that is grated with salt for an additional 50 yen. It seems to be suitable for days when you want to control sugar and calories, such as during sugar restriction or the next day after eating too much. Yudofu is said to have about 94% less sugar and 72% less calories than rice.
