we felt very welcomed by the friendly owners. everything was very well made especially the nigiris; there were so little rice compared to the thick pieces of fish. each roll had 8 pieces and were made fresh in front of us. 10/10 would recommend :)

Cuando mi amiga Barb me dijo, vamos a un all you can eat de sushi nuevo, pensé en omg sushi burritos, pero me sorprendió la calidad de su producto y la presentación solo sushi de muy buena calidad en un all you can eat, con un servicio estupendo, los duenos nos invitaron sake, y shots, en verdad se esmeraron en hacernos pasar un buena experiencia, se ocupan sus clientes, lo recomiendo ampliamente ademas bebimos sake y cerveza comimos delicioso y no rompimos la alcancía, muy muy recomendable!!!!

What a great place! Under new ownership, brothers Brian and Nathan, this place is awesome. Yea it’s All you can eat, but it’s different than the normal all you can eat places, it’s actually very good. I went with a longtime friend who lives in Costa Mesa, and lived here for over 45 years. He visited this place prior to the new ownership and was pleasantly surprised. As usual, I totally forget to take pictures of the delish selections, but was able to get a few. I do suggest a number of items. The gyoza was crispy after being prepared and was made to melt in your mouth. I had Salman, tuna, and Bluefin Toro, which was delicious. Not too much rice and fresh fish. Enjoyed a few rolls: Crench (so tasty), Salman Crunch Roll, Spicy Tuna Hand roll, and Sun and Kisses Roll, all worth the order. The Asahi beer was ice cold and a great compliment to our meal. Coming from Chicago I’m particular with my sushi restaurants, especially one that advertises “All you can eat”, but I strongly suggest this one, it’s so worth it! Thank you Brian. Great place. When you go, tell them Chicago Keith sent you.

Great sushi! The fun part of AYCE with the quality of a La carte. Their teriyaki salmon and beef was also AMAZING.

Delicious and affordable all you can eat dinner! The bluefin tuna nigiri and the monster roll were my favourite! Service was fast and the nigiris were served perfectly. There is a big piece of fish and a super small amount of rice, exactly the way it should be! I will definitely be returning!!

We came in for the all you can eat lunch. Food was excellent and the service was very friendly! My partner loved the mackerel sushi, and I was a huge fan of the garlic edamame and summertime roll.
