We've been going to Kiku for over 10 years. The fish portions are huge and the quality of the fish is A+. We've been to sushi restaurants all over OC and always come back here as our favorite. We've never had bad fish here. But only go if you aren't in a hurry. The only sushi chef has been the owner of the place since he opened it 15+ years ago. Family owned, slow service, but worth the wait.
