My husband and I came here for weekday AYCE lunch and were impressed by the food quality, flavors, and service.
Though the restaurant doesn’t have much seating, we only had to wait a few minutes for them to clean a table and seat us.
Our food came out fast and I got to have my favorites like calamari, eel handrolls, and salmon nigiri. The mango salad was also tasty.
We noticed that although the rules state they will charge for excess food, the waitress was kind not to charge a group of teenage boys next to us who over-ordered and were so terrified that they couldn’t finish their food. That’s great hospitality.

This was by far the worst sushi buffet experience I’ve ever had. The food tasted spoiled and had a garbage-like smell. When I told the waitress, she dismissed it and suggested maybe I’m “picky” and should just add lemon to fix the smell. Even the roe on some sushi tasted bitter.
We were told we could order three rounds and advised to order the limited “special” items in the first round — which we did. Unfortunately, they were all terrible. The octopus was rubbery and tough like leather. The sushi rice tasted old and stale. The seaweed around the rolls was clearly pre-wrapped long ago and smelled rotten. Some of the fish even had a yellowish color from sitting too long.
We couldn’t even finish the first round and told them we were still hungry but the food was inedible. They still charged us extra for uneaten items as a “buffet penalty,” which almost doubled our bill. The portions weren’t large — they were just bad.
To make things worse, there was a sign in the restroom asking customers not to throw food away and instead admit they couldn’t eat it, which made it feel like they expect this to happen and profit from it.
I’ve tried sushi at many places across Orange County and have never experienced anything this bad. We left still hungry, with a terrible aftertaste. Even after washing my hands multiple times, they smelled like garbage, and I later got nausea and diarrhea.
Absolutely would not recommend.

We heard about this new all-you-can-eat sushi restaurant, so we decided to stop by for dinner. In addition to the blue fin tuna sushi, the amebi sushi, and the scallop sushi, I would have liked to have seen sea urchin sushi as well. Compared to other all-you-can-eat sushi restaurants, they offer fewer appetizers. You should keep in mind that we did not receive miso soup and the udon on the menu is not included in the all you can eat menu. In terms of sushi selections, there were not many options, but there was a large selection of rolls. Considering that you order 3 rolls and you are pretty full, it would be nice if they offered a greater variety of sushi. As with the fish, it was fresh, but I was not interested in eating rolls. Overall the services were good and everything came out fast and clean.

Perfect casual spot to grab sushi with friends & family.
Parking: Free parking lot. Easy to find a spot.
Ambiance/Environment: It’s a very casual spot. They have a medium sized space with a decent amount of indoor seating. You can choose to sit at the bar or table.
Service: Everyone was courteous, quick, & efficient! The server checked on me a few times ensuring if I needed anything. Since I sat at the bar, the sushi chefs were also making conversations with me.
Foods: Their fish was fresh, smooth, and delicious! I absolutely enjoyed everything! I saw they’re most popular for the Lemon Pepper Salmon. I can agree, now I know why it’s so popular. My favorite rolls are the Mango Salmon special roll. The mango sauce was sooo good! It was a tad sweet but balanced well with the salmon. Although the bluefin tuna was limited per person, it was so delicious.
1. Diablo Roll (special rolls)
2. Mango Salmon Roll (special rolls)
3. Magnolia (no rice rolls)
4. Salmon Skin (hand rolls)
5. Popcorn Crawfish (baked & tempura rolls)
6. Mango Avocado Salad
7. Peppered Salmon (sushi)
8. Ikura (sushi)
9. Bluefin Tuna (sushi)
10. Jalapeño Bomb (appetizer)
Pricing: Definitely worth its AYCE price! There’s so many options in each category. I only lasted 1.5 rounds lol.

Went with a large group of friends to see how the All You Can Eat Experience would turn out! Wait was a bit long which was expected but our waitress did great and got us a table very quickly. She was very sweet and laidback as we placed in order for about 10-15 rolls, sashimi, soups, and appetizers. You can tell they were busy – but service was solid through and through.
The fish quality was actually not too bad! The Bluefin for all you can eat was top quality. I was VERY impressed and needed up getting 14 pieces of it.
Their craft rolls also had a plethora of options and all had some quality grade sushi. There were some that definitely needed sauces to amplify the flavor, but simply just asking the server helped. The Diablo, Mango Salmon and Popcorn rolls were definitely the top favorites of the night.
The appetizers were pretty standard and basic and can never go wrong with Gyoza or Garlic Edamame! The other appetizers like Miso Soup, cheese sticks, wings, not the best and can’t expect too much from a Sushi restaurant.
Overall, experience was great, one of the largest range of options for AYCE and again that Bluefin, definitely would be a reason to go with a big group. The more the better!
Definitely recommend and solid option!

This restaurant is All You Can Eat Type and had happy hour every working day. Honestly, the quality and taste of sushi were really good. We were three and had wide variety of sushi choices. Everything was fresh. The experience was beyond my expectations from an All You Can Eat place

I was surprised by how many options their happy hour menu had, the variety is definitely worth the price. They had tempura, deep fried rolls, seared salmon, and a bunch of other options. You order in 3 rounds, and most rolls are 8 pieces except a few that are 4-5 pieces. The quality was also very robust, especially for the price. The difference between the full menu and the Happy Hour is that the full menu gives you sashimi and nigiri (just fish, or fish on rice) on top of the rolls, while the happy hour is just rolls. The servers were also attentive and welcoming. I plan on coming back here again for sure, and I’d recommend trying it out.
