Zauo Fishing Restaurant Namba in Namba, Osaka, is a fishing restaurant where diners catch fish from a large tank and have them cooked. Caught fish are prepared as hoe, salt-grilled, soy-braised, or fried, and a drum is beaten to celebrate each catch. Walk-ins can get a table for the same evening at 8 p.m., and Korean-speaking staff are on hand. Fish can be hard to catch, and it is possible to go 40 minutes without catching a single one.
