Zauo has tables on long 'fishing boats' over tanks where patrons fish for their own dinner – particularly fun for kids, if they're not squeamish. If you hook something, there's celebratory drumming and your fish is whisked away to be prepared how you like (priced according to the type of fish). Dishes are meant for sharing.
Also on the menu: sushi, shio-yaki (salt-grilled), fish and deep-fried octopus. There's a ¥300 per person table charge. Reserve for a 'boat' table.
