Fish-your-own Zauo's quite a commotion and good, clean fun. Staff equip you with fishing rods, bait and nets to fish your own tai (sea bream), hirame (flounder) and more from tanks surrounding boat-shaped platforms equipped with tables. When you catch something, staff bang drums and shout before preparing your catch to your taste: sashimi, grilled, fried etc.
There are other izakaya-style dishes if fish isn't your thing.
