Fresh fish and great service. Packed on weekends. Not super fancy - dress casual. I brought a friend who travels to Japan a lot and is very picky about his sushi. He was impressed and really liked the Toro. My favorite is Salmon sushi. Love, love, love Gen Kai!

The service is honestly second to none. I have been to many restaurants from Northern California to Southern of all types and this was the best. Not only were they amazingly friendly and respectful but the food was great as well. I would strongly reccomend this restaurant.

This was one of the first sushi restaurants I ever had the pleasure of visiting. The staff is sweet, and the rolls are delicious! The space is a little cramped, but it adds to the atmosphere.

I've eaten at Genkai sushi 2-3/week since I was a young child and each time the food and service just seems to get better. The sushi specials are both fresh and tasty. All the fish is the very freshest. I've read several bad reviews, but as a regular customer for 29 years I must say that these are probably lies spread by other restaurant owners. When I went away for college, all I could think about was coming home to eat their toro, tuna, uni and aji. When I finally moved back into town, I just couldn't help myself but to eat at Gen Kai all the time. They have an excellent Sake list and they now have taught me the virtues of drinking soju (something like a Japanese vodka). I've been to several other sushi bars in Orange County and nothing can compare to the service and quality of Gen Kai. 5/5!

This place has huge sushi bar (20+ seats). The chefs are a blast. Creative, never before seen 'cuts'/rolls, etc. Dining room is also good but a little 'tight'. Sushi quality is exceptional! Fresh!
