Uoichi Shokudo

Uoichi Shokudo is a seafood restaurant near Osaka's Kizu wholesale market that serves kaisendon topped with tuna and uni. The mixed kaisendon can be ordered with added toppings such as uni, scallop, and chutoro, and the rice comes as plain white rice. It opens at 6 a.m., and customers order in advance from a menu board while waiting, photographing their order slip to be checked at entry. There are only four tables, so waits run over an hour.
