Sushi Maru Namba Walk is a sushi shop in Namba Walk that serves sushi and raw oysters. You pick numbered sushi tickets from the menu and put them in a container, and the shop makes them for you; the menu also includes engawa and tuna maki. Lunch menus and lunch sets are available separately, so it can be a midday meal. The wasabi is added in large amounts and is spicy enough to make your stomach burn.
