I came here around 6pm on a Wednesday night. I checked in by scanning the QR code and being placed on a wait list. We were 27th in line which took us (a party of 2) about an hour to get seated. I was unaware there was an online waitlist where I could have put my name down on open table to save a spot in line. Do this in advance if you don't want to wait! When we first got seated we weren't served or spoke to for about 10 minutes. Once we got served then our service was great. We tried the wontons, pork belly bun, white tuna, jalapeño bomb, sesame balls, crispy spicy tuna as appetizers and they were all underwhelming. The ones that we somewhat enjoyed were the pork belly bun and the sesame balls. We also got the spicy ramen, fast and furious roll, and the sakura rolls. The ramen was bland, the broth itself and the noodles did not have much flavor to it. The rolls were just okay. For nigiris, we got the basic tuna, seared tuna, salmon, and seared salmon. For an AYCE buffet, their nigiri's are larger than most which was a plus. You can't go wrong with the tuna and salmon nigiri! They were pretty good but I would steer away from the seared tuna and salmon unless you like sweet nigiris. The seared fish has a sauce on it that we didn't not like that made it too sweet. I also got the passion fruit drink which was the best thing I had on the menu. They use real fruit in this drink! Overall, I was expecting better with all the hype that was going around and was not worth the wait. This is one of the better AYCE sushi buffets I've been to in Colorado but don't expect to have high end small plates and rolls. read more

They said they could seat us right away but we ended up having another person. They said "a few more minutes" which is completely fine. About 15 minutes later we asked to see how much longer and they told us "35-45 more minutes". It's 20° outside and they don't allow more than 6 in their waiting room. Why would they not tell us how much longer it was from the start? We ended up going somewhere else. read more

Great service, lively atmosphere and cute decor. The service provided was fast and efficient. We arrived 15 minutes prior to opening on a Saturday, and a lengthy line has already formed outside but we were seated rather quickly. For the price the food was delicious. We sampled dishes from appetizer, hibachi, sushi and ramen sections and were pleasantly pleased with each dish. The ramen was perfectly portioned, allowing room to explore other menu items. They also offered 1.50 Coors light and 3$ 5oz hot sake. Despite the busyness, the servers were remarkably attentive. We will definitely be back in the future. read more

I've been waiting to try Chubby Fish, and even though it wasn't my favorite dining experience, I'd still go back for the unlimited sushi and price. We ended up going to Chubby Fish during their soft opening, and arrived 5 minutes after they opened on a Friday. A lot of the tables were filled up, but there was no wait. I'd definitely recommend going right when they open to avoid the long wait times that people have mentioned. The atmosphere was busy and upbeat. A decent amount of tables that fit all size groups. The robot that delivers food is super cute and the decor is fun. The staff seem a little stressed because everything is fast paced, but everyone was friendly. The sushi was good and the other food items were okay. I think the $29.99 deal is worth it for the unlimited sushi. if I go back, I would only order the sushi. All the rolls were good, particularly the rainbow roll. We even saw large tables ordering platters of nigiri and sushi. The other items were more about quantity than quality, but they weren't bad. You definitely get more bang for your buck by focusing on the sushi. Some of our orders got lost - we waited 45 mins for 5 pieces of nigiri (we kept being told it was on the way), but ended up closing out because the order wasn't put in. I think the kinks will be worked out in time, and that more servers will help. I will wait a bit for things to sort out, but I'm interested in coming back for a sushi fest of my own. read more

We've been hearing about this place from friends and we finally visited as a group of 8 for a birthday celebration. We made sure to arrive early (on a Thursday) since we also heard that they can get quite busy, but luckily we were seated right away. Everything seemed super organized. We were told how everything works and then encouraged to place a large order to get ourselves started. Each of us chose a couple items, but I'd recommend making your first order even bigger. Most of the options are fairly small, even the bowl of ramen was a small serving, but that works out perfectly so you aren't too stuffed to try more. The service was quick and friendly and imagine our surprise when a giant whale mascot came out of the kitchen and along with a couple staff and their robot servers, sang happy birthday to our friend! That was fun :). The price is excellent for the quality and amount of food. We will be back! read more

The wait is long during the weekend, so it is obvious that it is descent. We like to just go on the waitlist on open table before we head there. The ambiance is busy on the ceiling but a clean restaurant. The food is descent and not too long of the wait. Sitting at the sushi bar feels like you get served faster. We prefer the nigiri but the sushi rolls aren't bad. Just don't recommend the Japanese cheesecake, it is definitely just from a package that you can get at the Asian market. read more

Update on my review: Having dined here 20-25 times (and I'm not exaggerating), I've noticed a decline in the quality of the fish over time. I used to be impressed by the value for the price, but unfortunately, that's no longer the case. During my visit last week, the salmon nigiri was not fresh and was quite disappointing. If you're looking for a better all-you-can-eat option, I'd recommend Umai Ya, as their quality now seems to surpass this place. Also, their waitlist system is frustrating and poorly managed. The online system shows your place in line but doesn't provide an estimated wait time or arrival period, which makes it difficult to plan your arrival. When you check in at the restaurant, they might quote you about an hour wait, but then send a text 15 minutes later saying your table is ready, often after you've already left to run errands. The inconsistency makes the whole process inconvenient and unreliable. ALSO, they do promotions and raffles in exchange for good reviews if I'm not mistaken so beware of some of these 5 star reviews! read more

We decided to try Chubby Fish Sushi after hearing about the buzz, but honestly, I don't get the hype. We were number 41 on the waitlist and thankfully managed to skip the line by grabbing seats at the bar--and thank goodness, because waiting over two hours would not have been worth it. We ordered a wide variety of items: Pork Belly Bun - fluffy bun, decent flavor Truffle White Tuna - didn't taste any truffle Baked Green Mussels - delicious, but hard to mess up (they're good everywhere) Chicken Karaage - very okay Chubby Bite & Crispy Spicy Tuna - heavy Pork Belly, Shrimp & Lamb Skewers - the highlight of the meal; all were well-seasoned, juicy, and flavorful Phantasm Roll & Gold Philadelphia Roll - rich and decadent, but overly greasy and left me feeling a bit sick Assorted Nigiri - underwhelming; seared salmon wasn't really seared, rice and fish were both just "meh" While the variety was very appealing, the quality just didn't match the wait. The rolls were indulgent but lacked balance, and most of the meal leaned too heavily into oiliness. If I lived nearby and could walk in without a wait, I might come back just for the skewers. But as it stands, this place is not worth waiting hours for. The experience felt more like hype than substance. read more

Get ready to fill your belly, but also know you're going to empty your wallet a little bit too... But you won't be disappointed about it. The quality and quantity were amazing! They were able to do some slight customizations for our kids - which was a HUGE plus!! And the waiter, Jay (?), was patient and great with our kids. We appreciated the whole atmosphere for a super memorable birthday dinner for the newly 12 year old. Still feeling a lil chubby from the meal! read more

They don't take reservations but a waitlist on opentable, You must plan in advanced to get on the waitlist an hour before you want to eat since there's normally a wait. We went on Friday night, the opentable system worked as described, as it showed we were 5th, we started making our way to the restaurant and when we showed up, table was ready. The vibe as you walk in is pretty fun: the decorations, lighting, music and robots carrying food. Our waiter was attentive, explained the process and we got our order delivered really fast right after we gave him the paper with our selections. The food was delicious! The phantasm roll was our favorite, the classic rainbow roll always tasty and refreshing. Since we don't like tempura or cream cheese, the rolls menu started getting limited but we ordered some apps and nigiri. Really enjoyed the experience and will be coming back ! read more

They do not offer to go. You also cant call to order despite what yelp says. I say update the info, inconvenience. Just saying.

Came in on a Sunday just before opening (around 3:50) and even though the line was already wrapped around the corner, we were seated immediately once they opened. Ollie was our server and she was awesome--super attentive and friendly. The food was honestly a 12/10. We frequent two other AYCE spots and this one really stood out. The wait for food was a bit longer at first, but totally understandable since the entire restaurant placed orders within minutes of opening. Overall, an excellent experience and we'll definitely be back! read more

If I could give Chubby Fish 100 stars, I absolutely would. This is hands down the best sushi I've had anywhere in Colorado. From the moment we walked in, everything felt welcoming, bright, and incredibly clean. Even the bathrooms were spotless and fresh which honestly says a lot about the care they put into their restaurant. The huge flat-screen TV playing anime while you dine is such a fun and unique touch that makes the whole experience even better. The food? Outstanding. Every roll was fresh, beautifully presented, and packed with flavor. You can truly taste the quality in every bite. And I have to give a special shoutout to Juan, our server. His service was exceptional attentive, friendly, and genuinely caring. He made us feel valued the entire time and elevated an already amazing meal into an unforgettable experience. Great food brings you in once. Amazing service brings you back again and again and we will definitely be back. 100/10. Thank you, Juan, for making our visit incredible! read more

Cool decor. Great service. INSANE food. As someone from the coast, the fish was bomb. We ordered about 3 portions of the bao buns. Lychee martini was perfect. 10/10 would recommend. read more

friend recommend it. can't believe we don't have to wait 2 hours like last time we were here. Décor is lively and loud music popping! Staff are super friendly explaing the menu since is our first time. Was seated at the Sushi Bar so got to see them making the sushi and cutting a tuna! So many choices! The lamb skew was sooooo good!!! I had like 12 of it. The only thing I don't recommend is the Salmon Onigiri. The flavor is just not what we are use to. Will definitely be back if we are in the area and don't have to wait 2 hours. read more

What a great place to stuff your face! I just moved to the Denver area, and was looking for a welcoming all you can eat sushi place, this has been my favorite spot yet. The staff was super fun to talk to. (When they weren't busy) The place was neat, the menu has very diverse and delicious rolls, and the speed of service was great. They are often busy so being patient is important. I didn't expect to get the speed of service that I did. They work fast and the consistency of the rolls are perfect. The space they have is small, but they make the most of it. It is loud, but that's that I expected based on other reviews. Overall a wonderful dining experience all things considered. read more

A super trendy and awesomely decorated restaurant! It's in a small strip mall that has a large parking lot. Calling to be placed on a wait list is advisable but we were able to get seated right away without doing so. It's $30'ish apiece for all you can eat and the food and service are outstanding! The robots that bring you food to the table are pretty cool too! A draft beer (Sapporo) is $7 for the first one, and only $1 for the second. I highly recommend Chubby Fish! read more

We were extremely excited to try this place as I kept on seeing videos on social media. We got there at opening and there was a line. I was very hopeful seeing this! Walking inside, the decor and vibes are great. Unfortunately once we got our food, our experience changed. We ordered some apps and they did not seem to be very good quality. I was still giving it a chance since we hadn't tried the sushi yet. Once we got the sushi we immediately were not impressed with the quality. I ordered two albacore nigiri and the rice was the driest I've ever had. A lot of their rolls were fried and with cream cheese. Unfortunately we will not be back. read more

I had a coworker tell me this is the best AYCE sushi in Colorado, and I think they were right! I've had really bad AYCE sushi so I was skeptical going into this place, but gave it a chance. everything tasted really ~NORMAL~. For example, the takoyaki tasted exactly as it should, somewhere else it tastes SO off (too sweet, really gummy, and fishy). We specifically liked the crispy rice with spicy tuna and the volcano roll (no cream cheese). I would definitely recommend this place if you tend to order over $30/person at a sushi restaurant anyways. The decor is fun and the service is great. read more

Well worth the wait and definitely living up to the hype. This new AYCE sushi spot is in the restaurant formerly known as Sushi Umi. It has been opened for over a month now, but there is still quite the hype, which I can see why. We checked in around 4:30PM and was told 1.5 - 2 hour wait for a party of 2. We ran some errands and actually received a text after 1 hour that our table was ready; we were seated promptly once we came back. We were hungry and ready to order, so ordered everything all at once. To my surprise, the apps came out within 10 minutes and the rest of our sushi came out about 5 minutes later. I'm very impressed as the entire place was packed! The food was amazing! All the fish was fresh and the rolls had a generous portion of fish and toppings. All of the nigiri we ordered also had a generous portion of fish as well. I don't think you can go wrong with anything on the menu. It's also great for groups because there is something on the menu for everything. At $29.99/ person for dinner, it is a killer deal. I hope the quality and service keeps up. I will definitely be coming back. read more

This is a very fun restaurant. Everything is bright and upbeat. The staff is great, the music is lively, the sushi is great, and they offer a wide selection. I'm not sure how they do it for the price. It's easy to get to, and there is plenty of parking. Plus, they have a cool robot that brings out the food. I saw some reviews talking about wait times; I got there around the opening and was seated immediately. And a lot of other people were as well, but there was still plenty of room. I'm sure it ebbs and flows. It's good sushi for $30. read more

We came at 5 when they opened and there was a line. Took us about 45 min to 1 hour to get in. But once we got in service was fast and they have robot servers that makes it really neat. The ambiance was so cool and pretty. As for the food. I'm glad they came in little servings was perfect to try everything since it is all you can eat. We ordered a lot at once and they came out with this long board. Quality was alright but I still enjoyed the food. Except the chicken skewers. We did not like the seasonings they put on it. Other than that was worth it. read more

Chubby Fish Sushi - Nigiri - Sushi Bars Near Me - Denver, Colorado

The restaurant has a super cool atmosphere and that's why we wanted to try it. Service was good so this review is not against the people working... but the food was borderline inedible. The ginger was browning, and every single item we ordered either was an unappetizing color, or had an odd taste. We left feeling super bummed and resentful of the money spent. read more

Great for a night out! Great appetizers with even better sushi! The price is well worth the food with decent portions. Fish tasted fresh for a landlocked state (I'm from California). Don't be afraid to try everything but also get your sushi fill to make your money worth it! 10/10 will be going again. My only reason for the 4/5 stars is honestly the wait and process for getting in. If you are not there when opening or late at night you will be waiting 1-3hrs for a seat. read more

Dined in here during their soft opening, and this place was packed!! So glad I called in to make reservations because I overheard the hostess say the wait was about 1.5 to 2 hrs. I will have to say that I have to give mad props to the hostess. She probably had the hardest job of the night. Dealing with hungry, impatient customers is never easy and she held up quite well. The food here is really good! For $30 you get AYCE sushi, skewers, and ramen! I wasn't able to try their ramen but I definitely will next time. Their rolls and nigiri was delicious. The nigiri were perfect one biters; perfect amount of rice and fish. For the most part they tasted fresh with the exceptions of the last order. The nigiri seemed like they sat out too long. The rolls were also quite good. Again, the sections were cut in perfect bite size. The skewers were probably my favorite of the night. The lamb took the top of the fave list. I hope that in the future there will be more skewer options because the pork belly, lamb, chicken, and shrimp were all really amazing. The staff here did an amazing job with the chaos. The dishes came out really quick and I saw all them smiling even though the demand was very high. I think the longest we had to wait for anything was for the bill. I loved the robot server! This machine knew when there was people in the way, and the way it varied its speed is really touching to this nerd. I can't wait to come back and try other dishes. I can definitely see Chubby Fish being my 2nd home! read more

Watch out for robots!! Four robots were circling the restaurant delivering food and drinks. All you can eat sushi for $30 a person!! The sushi was delicious. Our server, Min was a treat and helpful. We did have a two hour wait which we spent at the bar next door. No reservations and no call ahead seating. Chubby's is fairly new and there is often a line at the door when they open. The wait was worth it. They have an expansive menu and a full bar. A server takes the orders and the robots deliver. Music is quite loud and is EDM dance music on loop. They have a sushi bar and they offer hibachi dishes. The decor is wild and colorful. The seating is tight but they can make a wheelchair work. We were there for a birthday and the robot sang and brought free shots to the table. Bathrooms were spotless. Parking is in a large lot. Manager spoke to us as we left. read more

They still have some things to iron out. The biggest being their waitlist. The reasoning for their lack of a reservation system seemed silly, but they certainly are not hurting for business. We waited for an hour to get seated mostly due to the fact that we had a larger party. As we waited we saw several people cross their name off the list who were smaller parties because they didn't want to wait any longer. The food was pretty good. The skewers were very tasty, pork belly buns were also yummy but lacked enough meat, we liked the spicy ramen, and maybe half of our sushi was good, the rest was okay. Service was extremely friendly but certainly chaotic. We had several different people waiting on us and one main server. Food came out at a slow pace and we had to keep reminding our server what we ordered and to please go check on our dishes. She also didn't bother to ask if we needed separate checks, which made it too much of a hassle at the end to split, so we each paid half. Front of house manager was knowledgeable and friendly and went out of his way to talk with us. He did his best to appease eager customers waiting to get in. The atmosphere is great! It has a downtown vibe even though the restaurant is in a strip mall in Thornton. Fun dancy club type music, a tokyo feel with tiny light up street signs hanging from the ceiling, cute decor, and fun tableware. The bathrooms could use more attention, but the servers are racing all around that they hardly have time to do anything else. The crowd is young and willing to wait to try the latest all you can eat joint. And even though it was past our bedtime, Chubby Fish is open until midnight. We got there at 6:40 and didn't leave until 10:30 due to all the waiting! I think this place has real potential. They were very sweet to talk with, and we'll certainly be back with an updated review once they're up and running a bit longer. I think a reservation system is still worth a shot--especially for bigger parties. Seems silly not to have one and then reserve the rest of the tables for people who show up at the last minute. Some paper ordering sheets could help the servers tremendously. If they allowed guests to check off what they want with paper and pencil and just have servers come pick up the sheet, it would expedite the process so much faster and avoid confusion when servers can't understand what you want or can't hear. read more
