Nakashou Namba is an eel restaurant in Namba, Osaka, specializing in unadon and hitsumabushi. Hitsumabushi uses eel that is crisp outside and moist inside, eaten with rice and finished with ochazuke, while unadon focuses on the eel itself. Orders are placed through a QR translation menu, and a bar table lets diners watch eel being grilled over charcoal through a glass window. The shop is easy to miss from the first-floor shopping street, so take the elevator directly to the fourth floor.
