    High quality fish and great portions. I wish there were more rolls that didn't have either cream cheese or fried asparagus, there weren't many fresh roll options. The sashimi and nigiri were great. The piece of fish on the nigiri is easily double maybe even triple the size of a typical sushi place. The size of the restaurant made us feel rushed though. We ate fairly quickly and wanted to chat for a moment but the hostess was yelling that they needed a table for two and when I looked around all the tables were taken so we left. If they had more fresh roll options and we didn't feel as rushed this would get 5 stars.

    Staff is helpful and sushi is delicious! We have enjoyed everything we've tried over the past year.

    Everything was surprisingly good for being in Denver, well Thornton in this case. The only thing I thought could've been better was the miso soup. It had umami but needed a little salt or soy sauce. Service was good and quick. The decor and atmosphere was on point. The chef even let me video him cutting up a tuna. The overall experience was pleasant. Definitely recommended.

    Yonsei is a new personal favorite of mines and I'm so happy that it's like 8 minutes away from us. This might be the best place for sushi in Colorado (even better than some places in Cali). Prices are reasonable and the fish tastes fresh. You do not need to pay an arm and a leg for sushi in Colorado. If you're from Denver, this is worth a drive. This is truly a hole in the wall. First off, I love the whole samurai theme from the decor to the name of the rolls. Second, the staff is fantastic. They're so sweet and attentive. The sushi was fantastic. Each roll felt like butter and melted in your mouth. The unagi was so delicious. The toro was well done. We ordered the ronin and black samurai and they were so tasty. The salmon and hamachi tasted really well together. Truly a sushi wizard. Even something as simple as the spicy tuna roll was phenomenal. The mussels were drool worthy with enough cheese and spices. I'm not a big seafood fan so I love it when I can't taste the sea. My partner and I plan to try as much of the menu as possible. This is our go to place for sushi in CO.

    Wanted to check out the Sushi scene in Thornton, I was impressed with the 4.9 Yelp rating after 80 reviews. First off, if I could give 3.5 stars that would be my preference but unfortunately Yelp does not allow half star increments. The restaurant itself is fine, the staff are friendly, the interiors is very clean and relaxing, and the prices are solid. Why the 3 star rating then? My wife ordered the chirashi bowl and I went with a variety of nigiri orders. The slices of fish were very generous so thumbs up there. The quality though was where I had to knock it down a bit. The fish itself was not premium sushi grade in my opinion. The uni wasn't high grade or really fresh. The tail section of the ama ebi was..shrimpy in flavor. Premium sweet shrimp should be briny and sweet, not shrimpy in taste. The heads though were fried perfectly. The Nice drink menu and we found a great sake to share. The Unagi Eel was good, and the scallop mayo was nice. Overall it was okay, the prices were great, the portions were generous, and maybe we will try cooked dishes next time. I do want to support them and try again.

    20260207 table two around 7pm While living in Japan for 3 years and then moving back to the states I've been trying to find a place and that fresh sushi and tasted amazing. And this right here was by far the best sushi spot I had in a while. The food was amazing the staff were friendly. My only criticism would be having booster seats and a kids menu. That is all. I will be coming back here. PSA have a reservation this place gets packed

    Rolls!!

    I was impressed. The sashimi was especially fantastic! All of the rolls were good. This place and Hana Matsuri are my two favorite places to get sushi in the area. The place itself is small, I like the decorations and overall vibe. It's kind of hipster, with the decor, reggae music and cost. You can tell the people who work there care about your experience. The food came out well spread out, so you continuously eat. Our waitress was nice and always had a smile. I will be back & I definitely recommend you try it. Happy eating!!

    WAY overpriced & barely any food. Apparently their Bento Boxes "used" to be $14 & are now $18-$20. I still decided to give them a shot. Food was mediocre if anything. Shrimp tempura & miso soup were not that great at all. Didn't even eat the soup it was so bad. I give this place a HARD PASS.

    The food quality was superb. And the portions were substantial and exceeded the value for the money. The service was fantastic. Everyone was very attentive and our food arrived in a timely manner. This place is small, but clean, comfortable, and not loud, even when full. We will definitely go back!

    Omg everything was delicious the chu-toro was melt in your mouth. All the rolls had so much fish in them and also the fish was the freshest I've ever had in colorado and maybe even east coast? Service was friendly and non invasive. And the atmosphere was great i think they partnered with an artist: tokyo hiro? For their logos and storefront design. All in all best sushi in colorado hands down.

    Hands down the best sushi I've had in Colorado. I was craving sushi and tempura while out running errands, so I turned to Yelp. Luckily, Yonsei was less than 5 minutes away, so we thought we'd check it out. So glad we did! Let's start with the sushi - wow! The salmon and tuna were amazing, the specialty rolls had ingredients that complimented each other perfectly (and it didn't feel like these rolls were packed with stuff just because), and each roll had just the right amount of rice. All the rolls were good, but I particularly liked the salmon avocado roll and the Shogun roll. I also appreciated that there we lunch specials on Saturday. I went with the Huli Huli Chicken Bento. The bento box had so much for the price. The shrimp and vegetable tempura was light and crunchy (not overly breaded, which was fantastic, the chicken was super tasty, and the soup/salad rounded off the meal perfectly (bonus points for the 4 pieces of California roll too). Everything was so good and appropriately priced, the staff were so friendly and helpful, and the vibes were good. So excited to come back and try out more!

Looking forward to coming back again.

    I've eaten sushi in probably a hundred different cities between California, Oregon, Washington and…read moreDenver and I can say this one is pretty mid. This is attached to the mall so don't come here Thinking you're going to have sushi somewhere that feels authentic because it definitely feels like a mall restaurant. But if you want some sushi I do recommend it. I judge sushi mainly based on two things - obviously the quality of the fish or seafood, but also the rice. Presentation can be whatever since I don't eat the presentation. Either way, Between my party of four we had 11 different rolls and an appetizer and no complaints there with the fish, So that was great. Really was not impressed with the rice though. Just could not taste fresh, really was not sticky. Couple of rolls that my friends had not wrapped in seaweed fell apart pretty easily. Also, minimal ginger and wasabi given with your rolls. So that could be a pet peeve of mine. An $18 glass of Japanese whiskey and that was fantastic. I got the last of the bottle and it was perfect with a heavy pour. Service was great here. Our waitress was attentive and checked in on us often anytime she walked in the general area. I'd love to come back and try it again And hopefully give a better score.

    I was craving sushi and wanting something close to home when I found this place via a search on…read moreGoogle. It had high ratings so I read reviews which influenced what I ordered. I ordered the Red Dragon roll, the champion sashimi, and the Denver roll to go via online ordering through their website. The ordering process was not ideal for a first time customer because none of the items had descriptions so I was looking between their website and then the ordering platform. Once you order it gives you a time frame but I never got another notice when my order was actually ready which wasn't ideal. My order was correct and packaged very pretty for takeout. The Red Dragon roll was just okay. In my opinion, the tuna on top of it is sliced very thin, so it's not much of a show stopper especially for what they consider to be a special roll. It had a lot of rice. It was fine but I don't think I'd order it again because it wasn't memorable in my opinion. The champion sashimi was kinda spicy which I didn't expect but it was delicious. I would order more of this or something similar to this preparation next time. The Denver roll was refreshing. It's wrapped in cucumber and it comes with a special sauce. I liked it. It was pretty filling too. I could see myself ordering that again if I'm craving a lighter option. I'd order the champion sashimi again and try something new next time for my second option.

    I'll admit it... I was skeptical about all you can eat sushi…read more Usually when I hear that, I expect quantity over quality. Chubby Fish ended up changing my mind. Everything is made to order, so nothing tasted like it had been sitting around. We ordered a mix of rolls, nigiri, appetizers, and dessert, and it all came out fresh. The pork belly bun was probably my favorite surprise of the night. I also really liked the gyoza, volcano roll, and the seared tuna nigiri. And if you have room, get the strawberry bingsu. It's a really good way to end the meal. One unexpected bonus was the little robot bringing food to the table. It's a small thing, but everyone around us seemed to get a kick out of it.

However, the service wasn't the friendliest and was disappointed of how slow the delivery of the food was and the delivery of it. For example, in our first round, we ordered sushi, chicken and fried rice to go with the chicken but the fried rice never delivered and we waited a while (30 min for everything except for the rice). Around 15 min after we ordered, we asked about the rice and they said they'd check, coming back they said the kitchen was backed up. After the 30 min, we asked about the rice again and the person serving us seemed agitated and dismissive and then left without providing alternatives or accommodations. The chicken got cold and we just ended up paying and left after that first round. The person serving us knew that we barely ordered anything and didn't say anything when we decided to just pay and leave. I would just say don't go during busy hours. I'm sure it may have been better outside of that time, however I have been to places that still give great service despite that. I don't think I'll go there again though.
