    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.

    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.

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

    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.

    Hand Nippon Roll, hand Yonsei Roll, Uni, Tobiko, Unagi, various rolls.

    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!

They have the breakfast staples but also some specials that are creative and delicious! We've had nutella crepes, chicken fried steak, breakfast burrito (which is massive!) and a special of the day - strawberry cheesecake waffle. All the ingredients come together perfectly and melts in your mouth! The one thing you HAVE to get is the cinnamon roll. Eat it while it's hot and gooey, you won't regret it! Next time I'm going to get the Salted Caramel Cinnamon roll. On Friday and Saturday they are open until 8 pm so you can enjoy them if you're unable to make it during the lunch hours!

It was getting pretty late, which can always feel a little awkward at some restaurants, but the staff was super welcoming right off the bat and didn't rush us at all. The place looks great inside, too, really nice atmosphere and modern decor. We started off with some drinks. I had the Michelada, which was killer. Spicy, savory, and refreshing exactly what I wanted. My wife got the la tradicional margarita, and she loved it. You can tell they use decent tequila and fresh lime, not that sugary pre-made stuff. The food hit the spot, too. My wife ordered the Birria Tacos, super tender meat, crispy shells, and the consommé for dipping was rich and flavorful. I went with the Poblano Chicken, and it was delicious. The sauce was creamy with just the right amount of roasted pepper kick to it. Big shout-out to Daniella, our server. She was a total sweetheart and took great care of us even though it was late. If you're in Broomfield, definitely give this place a shot. Good food, good people.

Don't get me wrong, it wasn't dirty or unkempt in any way, but it had that old, hole-in-the-wall kind of feel that can either be a good thing or a bad thing. Well, it was a good thing. I'm so glad I gave this place the benefit of the doubt! The server (Jamiee, I think) was very friendly and attentive. I love Mexican food, and I'm kinda picky when it comes to the little things like sauces, chips, guacamole, salsa, etc. For me, that's usually a pretty good barometer for how the rest of the food is going to be. I ordered chips, salsa, and a side of guacamole to start. The chips were homemade, and soooo freaking good -- thick and crunchy, but still had a light texture. The guacamole was absolutely top shelf -- creamy but not runny, and just the perfect amount of spices, tomatoes and onions. The salsa had a decent kick, but nothing crazy. It was really good, if not a smidge on the runny side. The star of the show here was the smothered burrito. I ordered mine with carne asada. The sucker was huge, and loaded to the rim of the plate with a green chile sauce that was just, well, ridiculous. The melty cheese on top, with tomatoes, lettuce, and a respectable dollop of sour cream on the side, was a full-on party for my tastebuds. Why the 4 stars then, and not 5, you might ask? Well, the carne asada was a bit too charred for my liking. Just a few too many crispy/crunchy pieces for it to be perfect. The chunks that weren't crispy were super tender though. I just wanted more of that. Got a mango shake to go, made with hand-scooped ice cream (not soft serve). It tasted good but blended way too long, to the point of being runny. If I lived anywhere near here, I would 100% go back, not even a question.
