Great all you can eat sushi spot! They have so many menu options including appetizers, hand rolls, nigiri, sashimi, regular rolls, and dessert. They even have rolls without rice for anyone who is carb conscious. Service was great - our water was refilled quickly and our food came out very promptly. Some of the appetizers left a lot to be desired - like the French fries and chicken nuggets. But honestly what do you expect when you order fries and nuggets at an AYCE sushi place lol. Apparently a pretty popular spot because we came here on a Thursday evening and I most tables were taken. The sushi is not Michelin quality but it gets the job done and for $40 it is actually really good! Would definitely come back again if I'm feeling glutinous but don't want to break the bank on sushi.

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. They had a good amount of hand roll options too. The protein and Salmon hand rolls were a good size and good option. 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!

If I rate the food alone it's a five star from me!! However as a restaurant in total I felt the need to mark a star down. The presentation of the food could use a little more work, the plates made me feel like I was at a cheap asian buffet with high quality delicious sushi. I got some scallop nigiris and the presentation of it made me feel a bit sick, call me dirty minded but the option if sauce just was not it (taste wise was good I love scallop nigiris, but why did it have to look like that it honestly ruined the meal for me in the end and made me feel little sick looking at what I was eating I could inly eat one piece after thinking I could finish them only to find out it was mostly the presentation that made me not want to eat anymore xd) Service was great, loved how we were walked throughly of their menu, the waitress helping us used a pencil and circled everything while she explained how their service worked which I personally have never experienced from any sushi AYCE restaurants, they normally speed run it and just leave you without answers. Also, would be nice if they mentioned that they had miso soup and that it just wasn't on the menu!! Had to hear another customer ask about it for us to order it. Ambience is nice, however when me and my friend went a family had a very very loud crying baby the entire portion of our meal, I know being a parent is stressful but the restaurant is fairly small to where with little groups you can pretty much hear everyone talking (there were only four groups of ppl including me and my friend and three groups were groups of two and then the family. I am not a mom, but if your baby is screaming at the pitch of ringing to the ear indoors at a small restaurant please walk them outside for a little. I am mostly ranting but they left an entire mess on the floor as well.... Did not really help the ambiance for our first experience there.... Every time I tried talking to my friend it was screaming ringing my ear at a very very high level.. I kind of wished the workers said something for the other customers trying to enjoy their meal out. They also have a bar for solo diners which I love because I often go eat out alone I definitely will come back, it is a bit pricey for not as much variety compared to other sushi places but I loved how small the rice portions were here!

Food is decent and portioned well to ensure you can try as much food on their AYCE menu. Service was great and responsive but then it was an early dinner at 5pm on a Tuesday. Ambiance not so great furniture a bit old, supplies are laid out close by the dinning area but then I lived in Japan small places like this one focus on quality of their food and service. I appreciated small places like this that have clean and tidy bathroom. It tells you a lot the health of the restaurant.

We have winner for the Fish/Rice Ratio AYCE Sushi Spot!!! I wont go into too many details, because most places are so similar. First. Service. We came here on a Wednesday (11/27), and the lady with the short hair, was great. So polite and quick. When I said we would have 5, but dwindled to 4, she had no issues. When a server makes me feel at ease, when I have my own anxiety on taking more space, or causing inconvenience for people who are just doing their job... that's Tops. Fish was on par for AYCE spots. Cuts were a little messy, but that doesn't detract from the flavor. Rice Ratio is the best in OC without having to get Sashimi. Carb watching? They got protein/no-rice rolls. I'm big on reminding people that spots like this have the best chicken wings. This place has great chicken wings. Hot. Crispy. Yet juicy inside. Please try. One thing that no AYCE spot has seemed to avoid is that wet-towel, bleach/cleaning solutions smell. It does fade as you stay in there, but its apparent when you walk in. Tip that I'll reiterate: Happy Hour is only for Rolls. If you want Nigiri, you will pay the Lunch/Dinner Price. If you're a roll person, then HH from12-4, Mon-Thu is perfect for you. WILL DEFINITELY BE COMING BACK!!!!!
