While staying at Hyatt House, across from UC Colorado Anschutz Medical Center where we had an appt, we were looking for something light to eat since we had a late lunch on our flight to Denver due to a delayed flight. There doesn't seem to be much near the hotel within walkable distance. Searching online I found Kassai Sushi that was open late and place a delivery order from their website. If you're choosing delivery, use their website because the prices are slightly lower. For example, the Dinner Box "B" I ordered was $27.95 on the restaurant website, and the same thing on Grub Hub was listed at $31. Dinner Box "B" is a nice sushi/sashimi combo : 7 pieces of sushi, 7 pieces of sashimi, and California Roll. It also comes with soup, rice and salad. When I placed the order for "ASAP", they gave an estimated delivery time of 45 minutes, and the order arrived on time. The driver met me outside the hotel front entrance. The sushi was good! Some of the sashimi was sliced in an odd way I had never seen before... they were wide, long, and thin. Still tasty. I like how they packed the soy sauce in little cups, as it gives some place to mix in wasabi. I also don't like dealing with all those little soy sauce packets that are usually packed in take out. The orange cup contained the dressing for the salad. I'm not sure what flavor it was, but it was good. This is a big meal and will definitely fill you up. read more

This was easily one of the most unpleasant meals I have had in a long time. The experience went downhill the moment I walked into Kassai Sushi. The restaurant smelled noticeably fishy and unwelcoming, which is never a good sign for a sushi spot. seeing a 4.8 star rating on Google, I decided to give it the benefit of the doubt. That turned out to be a mistake and I should have trusted yelpers (3.8 stars - a terrible rating for as compared to surrounding sushi spots) Both sushi chefs behind the counter had headphones on and were completely preoccupied, working with their heads down and making no effort to acknowledge customers. It set a disengaged tone right away. The menu was extensive but frustrating to navigate, requiring constant cross referencing between the sushi menu and the regular menu just to understand what ingredients were included. Unfortunately, my biggest mistake was ordering the tuna nachos. The dish arrived as mushy, fishy tasting tuna drowned in mango and heavy sauces, completely soaking the wonton chips. One bite was enough and I sent it back - I gagged and almost threw up. We ordered several pieces of nigiri next, and the chef mistakenly prepared smoked salmon instead of regular salmon. What followed was even worse. The fish was stringy, extremely stale, and outright disgusting (apologies in advance for the photo of the stringy fish - this was also another gag moment). I also tried yellowtail that was intensely fishy and unacceptably stringy, pointing to low quality fish and poor preparation technique. The scallop is low quality made up of stale bay scallops. The new style salmon was just as bad, but at that point we did not bother sending back any more dishes. The hot dishes were no better. The fried pork chop was very dry, especially around the edges. The grilled hamachi head was overwhelmingly fishy and not properly grilled. Luckily we had plenty of lemon to make it somewhat tolerable. Service was mixed. The lone waitress was kind and clearly overworked, handling all the tables as well as take out orders - sheas great. Another staff member was on the phone the entire time. When we paid and left, the sushi chefs did not notice and remained absorbed in their music. Overall, this meal showed serious issues with fish quality, preparation, seasoning, and attention to customers. The chefs would genuinely benefit from tasting their own food or visiting nearby reputable sushi spots to better understand balance and technique. Never again. read more

If you're looking for your new go-to sushi spot... this is it. Decorated so cozy with details that make it feel warm and inviting the second you walk in. I love the dynamite roll... Perfectly balanced, a little crunch, a little spice, and packed with flavor. This place is highly recommend if you're a sushi lover. Homey the vibes and the service is kind and consistent every time. read more

Great great spot! It's kind of hidden in a small plaza in a neighborhood, but those are the best! Ample parking and they have happy hour! Since it was our first time, we missed it....next time! The interior wasn't too bright, which gave it a nice ambiance. There weren't many people (surprisingly since it was happy hour time), but the service was a tad slow. It took a while for them to take our orders and realized that it was just one waitress working. The entrees seemed like forever (maybe I was realllllly hungry), but when it came all worries went away. The Tokyo roll was phenomenal! The fish was fresh and it just didn't have any extras on it. Just fish and rice! Yum! The yellowtail jalapeno roll was pretty basic, but still delicious. I loved the small hint of spiciness (could've been a little more for me), and just yellowtail. I love that it wasn't packed with rice and less fish. I appreciate that! That was more than enough food!! Thank goodness I didn't order more! My boyfriend ordered his usuals, PA roll and salmon roll - boooooring! lol jk. He makes everything easier. Will definitely come back for happy hour and just come back in general!! xx read more

It's been quite a few years since I've been to Kassai, they've done a beautiful job 'modernizing' the restaurant. Dinner was very delicious! Parking can be a little tight if very busy, Kassai is a comfortable restaurant where they provide very tasty sushi, sashimi and rolls. We both had miso soup to start, split their sashimi deluxe combo entree, and had four rolls, New York where I was born,Tokyo where Glenda was born, Bomb Ash, and Jazz. We took a little of each as a leftover for later and to share with Louie, our Tuxedo Cat. All in all, an enjoyable dinner with fresh fish and excellent presentation. We will return, sooner than later. read more

Yet again, Kassai delivers an amazing dinner experience. We've never been disappointed by food or service. They have killer quality and it is so refreshing to come back to a staple and know you'll get what you're expecting. I will forever be convinced that the only reason this place isn't absolutely packeddd is because of location being off the beaten path. Quality, price, service 10/10 read more

Came in for our first visit. Parking spaces should be available most times of the week. Not too busy on a Saturday night. The food was good. They almost met my expectations of amazing. The service was the same. Good versus amazing. The ambiance was chill with the vibe inside. At one point someone was cleaning with some very strong smelling chemicals. Talk about a scent you do not want to smell while enjoying dinner. We may come back for more in the future. But most likely will only visit a couple times a year. I have higher expectations when spending $100 bucks with tip. read more

Great spot, kind of hidden but the sushi was amazing. Went here for a first date and we shared everything. Highly recommend getting a large hot skate to wash down the sushi. Date night? Great spot, not too busy and can be a good balance of openness and privacy. Waiters were also very nice and made sure we were comfortable. No second date, but at least got to try a new sushi spot. read more

Lexi & I went here last night for a sushi date! And like usual it didn't disappoint! The Mexico roll is my favorite and I will get it every time. The gyozas were crispy and flavorful! Lexi loves salmon so she always gets a roll that has salmon and of course the salmon nigiri! Our server was excellent! She was nice, and attentive! Anytime we need sushi this is our favorite spot that isn't too expensive! Dan & Lexi read more

Doordash review for Kassai. Honestly the sushi was decent for the area. I know sushi generally more $$$ than other cuisine but I did feel like for a $50 meal (3 rolls), the size of the rolls and quality of the fish could have been better. I did not like the jazz roll as the black pepper taste did not mesh well with the tuna. The other rolls were decent, but nothing mind blowing. I also think they were using overcooked rice cause some of the rice in the rolls were crunchy af. Wished my to go order came with complimentary miso soup or house salad, but I might have been spoiled by sushi establishments back at home. read more

I ordered a teriyaki salmon bento box. The soup and salad was good. The California roll was good. But the piece of salmon was really small and over cooked. And the yakitori was inedible.

I've eaten here 2 times, so I decided to right a review after my second experience. My first experience I give it a 3 out of 5 and decided to give it another go because it was close to where I live and needed a quick meal before work and flight the next morning. Why the one star review? Food Poisoning. This was my first meal of the day after working night shift and I was back for a second night of work. I ordered the spicy scallop, Tokyo and Manhattan roll. The Tokyo and Manhattan roll were mediocre at best, typical American Japanese sushi where the sauce and extra ingredients over power the overall taste of the sushi. Fish was decently fresh and wasn't fishy. The tuna wasn't that deep red and obvious and was ok to the taste. The spicy scallop roll was where it went wrong. This was the only roll my gf did not eat and she was fine the whole night and next morning. I ate about 3 or 4 pieces of the roll until I noticed a bad taste, it was bitter and did not have the sweetness from a fresh scallop. The first bite was bitter, and then the final was rancid. I thought it was me at first but it was obvious that the scallop was bad. I went to work and by 9pm I was wretching and having the runs. I work as an RN and I knew it was the scallop roll and that I contracted food poisoning from it. I vomited 4 more times and was stuck in our staff restroom for 30 minutes. After 2 barf bags later and 4 BMs later, I went home. Adding insult to injury, I had a flight to Norway the next morning that I had to endure. What a way to kickstart my vacation in September :) The bathroom was terminally cleaned for the rest of the staff to use . read more

Can't even finish. Afraid the food will make me sick. Should've known better getting sushi in Denver but I gave it a shot. Waste of money

Horrible bad fish. They have no customer service and only care about making a dime. Yucky not safe to eat.

I gave them another go and happily increase my stars to 5/5! Ordered off DoorDash on a Tuesday night and my food was ready & delivered quickly. They put a cardboard box under the sushi container in the brown paper bag in came in to ensure the sushi stayed nice and intact. Very thoughtful! I tried 2 new sushis from my last visit, and was happy to see they were much bigger than before. In the attached photo I had transferred the sushi to a platter so you can see the ingredients better. MIA roll (left) - shrimp tempura, cream cheese, jalapeño, topped with spicy tuna. Not too much cream cheese, generous amount of spicy tuna. Jalapeño gives it a nice crunch and punch! New York roll (right) - tuna, avocado, topped with salmon So good! Can't wait to order again. read more

良くない this means not good in the language from the Rising Sun. We have been coming here for years but the last 3 were AWFUL here is the list from tonight 1. Order in writing and explained the spice edinamie for an appetizer a. Brought when they served main course and it was barely warm b. 43 minutes 2. Again we ordered in writing the spicy toro roll $16.95 a. It was NOT brought out so the waitress asked if we still wanted it DUH b. After we had finished and were sitting for about ten minutes waitress asks if we still wanted it (really?) 3. My wife ordered and point out on the menu she wanted a Pinot Grigio and got a Pinot Noir instead (replaced about 5 minutes later) 4. Oh you want napkins ...half way through our meal we each got one flimsy napkin 5. Had to ask for wasabi It was not crowded in fact there were many wait staff standing around. NO HERE COMES THE WORSE IT SMELLED LIKE BAD FISH....HOPING I DONT GET SICK TONIGHT read more

I really wanted to like this restaurant a lot more based on recommendations from a close friend. Overall the experience was fine but I believe could've been a lot better. They appear to be very short staffed which added to my 2 star rating. We all received menus but explanations of the different types of sushi and what was included was not very clear. The The sushi was good but the rice wasn't packed very well, it would fall apart on picked up with either chopstick or your fingers. Once the waitress took her initial order we never really saw her again so we didn't get refills of any of our drinks without getting up to ask. We also had to ask for more napkins chopsticks etc. my wife got the teriyaki chicken which was actually really good probably the best food out of all of our orders. I will definitely get that again. I may try this restaurant again in the future and hopefully they'll be fully staffed so I can get a better feeling for their customer service. read more

Kassai Sushi - Sushi Bars Near Me - Denver, Colorado

Perfect neighborhood sushi spot near Lowry and Central Park. Recently dined in after a snowy week on a Friday night with a group of girlfriends. We ordered off of the specialty menu near the bar - Mars roll, Ninja Roll (Shrimp tempura, spicy tuna inside;eel and avocado outside), sashimi dinner 15pc, calamari appetizer, dinner box B, yakitori appetizer, some other specialty nigiri/rolls and an Oyaku donburi. The quality of the sushi is good but not the best. The sashimi looked great but definitely didn't taste as fresh and I probably wouldn't order of the sashimi 15pc dinner again. Unfortunately there was definitely not the freshest taste and not a lot of flavor. I do suggest ordering the calamari appetizer and other Japanese dish entrees that are cooked. The calamari appetizer was delicious and perfectly seasoned and fried. On that night of dining in, the yakitori appetizer was dry and difficulty to chew but still tasty. My friends love this neighborhood sushi spot and I would go back because of the friendly service and nice dining atmosphere. However I would go to other sushi spots nearby or in the Aurora/Denver area if I had the option or I would order non sashimi, sushi items or cooked items. In the past I've ordered take out and other items on their menu like their Chicken Katsu, tempura, hamachi kama, Katsu don, unagi don and more. I do recommend ordering the hamachi Kama or the tempura. They also have a good miso soup and salad with a delicious house made ginger dressing that comes complimentary with some dinner sets. The restaurant does do a great job with take out and packaging with care. Dining in: The staff was very accommodating and very friendly. On a Friday night parking was a little challenging, and a little icy in the lot but definitely recommend carpooling if in a group due to limited parking on a busy evening. read more

"Never judge a book by its cover." Well, Kassai Sushi is a prime example of that old adage! SPACE/ATMOSPHERE: Upon parking it looks like a little hole in the wall sushi joint. Not the kind of place I usually frequent for a sushi fix. However you walk in and everything is sleek and modern. Just what you'd expect in fabulous sushi restaurant! EATS: Everything was fantastic! I noshed on the Spicy Crab, Fire Cracker, and Mexico rolls. My eyes were faaar larger than my stomach, so I had leftovers. The Spicy Crab roll was a simple spicy crab mixture with seaweed and rice. The Fire Cracker roll had tuna, jalapeno, and avocado inside, tempura crunch and sriracha sauce outside. Now the Mexico roll was Spicy tuna, cream cheese, and jalapeno, deep fried w/ special sauce. The sauce was a bit sweet to complement the spicy filling. It was delish! I enjoyed all the rolls immensely. DRINKS: There's the usual line up of Japanese beers and sakis. I opted for a small Sapporo. It was the perfect pairing for my sushi meal. They have a Yelp check in offer for a free hot saki! So def redeem that it you're feeling adventurous. SERVICE: The service was great! Servers were very attentive and offered to answer any questions I had over the menu. They checked back with me to ensure I was enjoying my rolls and also inquired about which were my favorites when I was done. So nice! PRICE: Eh. It was just a tad higher than I would've expected. By a couple dollars or so a roll (anywhere from $5 to about $15 a roll, yikes). I'd highly recommend coming here with some friends so you can sample a few different rolls! Or dine in between 4:30 pm and 10 pm for their daily sushi happy hour!! Sometimes the best things are in unsuspecting places. I'd def recommend checking our Kassai Sushi next time you're in the neighborhood! read more

I first ate here the other week, in person. I came with 2 of my friends, and we had one of the best meals we'd had in a while! I got the Yellowtail Jalapeño (one of my all-time favorites), a few pieces of the happy hour sashimi, and a fried banana with mochi ice cream for dessert. It was so neat because our server arranged my fried bananas and mochi on the same plate in a really cute and fun way. The service here was impeccable, as was the sashimi/sushi. The server made many well-placed suggestions that led us to try many new things during our meal, including 3 different types of saké! The first bottle was free (due to the awesome Yelp! check-in special going on right now!), and our waitress suggested the next 2: one lightly sweetened, sparkling floral saké, and another lightly sweetened plum saké. Both were chilled, and really good! Ordering delivery from here tonight is an honor! (Note: I went with the Poke, 18pc Sashimi Platter, and fried bananas for tonight's order.) read more

Yummy lunch specials, super friendly staff that are always cleaning. There are a ton of unique fancy rolls- loads of spicy options.

This place is great for the area, I just feel like the the sushi isn't very good quality. It's definitely on the lower end of the spectrum especially with the prices they charge. Maybe they need a new distributor because for the amount I paid I am very disappointed, there was drama going on between the servers. They seem to prioritize to go orders more then people actually sitting in the restaurant. Hopefully it gets better. There main entrees are all consistent and good though, I would stick to those! read more

First impressions: The restaurant looked nice and the menu sounded good, but smells like fish as soon as you walk in. Food: The food definitely looked and sounded better on the menu than it tasted in real life. I wouldn't say that it was bad, but didn't have the freshness and flavors I was expecting. I was hungry enough to eat it though. Otherwise, the menu had a variety of choices, good prices, and good portions. Service: The server was really nice and friendly. No complaints about the staff or service. This wouldn't be my first go to for Japanese food, but I wouldn't be opposed to giving it a second chance. read more

Solid sushi place. Servers were friendly and efficient. All of the dishes were tasty, portions were larger than expected! Presentation of dishes was average. Spices Girl roll- jalapeño, tuna, wrapped in soy wrap Tokyo roll- spicy tuna inside, yellowtail and avocado outside Salmon sashimi- large slices, fresh! Agedashi tofu- big portion for only $5!! Lots of bonito shavings Salmon collar- deep fried, super crisp skin, could maybe use some salt Dessert- fried banana came in slices, tempura fried, drizzled with chocolate and whipped cream. I think the banana slices had been previously frozen? But still sweet and tasty. Mochi- mango and cappuccino, both yummy ALL of this plus a big Sapporo came out to around $65 before tip and we were both quite full. Quite a deal!! We will definitely return. read more

Okay, irrespective of the fact that their nigiri is just a skinny piece of fish on sushi rice, two of us got violently ill 6 hours after eating there. Based upon our Gross observations...we are fairly certain that what made us ill was their salmon skin roll. We have tried to reach out to them. They do not have a legitimate website. They have no contact email. We called several times but only got a voice message. No call back. Please keep our experience in mind before deciding to eat their food. read more

We wanted to scratch off Kassai Sushi from our "romantic restaurants list" for Valentine's Day Tour 2021 for Nick & I. The restaurant was beautiful inside, super intimate space to get into lovey-dovey talk with your significant, special other or whatever.. The staff were incredible, and definitely trying their hardest to really make our dinner special.. The staff, although sweet, were sooo far behind on online deliveries and just couldn't make our 7:00pm "reservation" to work. I called to make that reservation and the restaurant didn't even take reservations! Just that they promised table vacancy, as it is NOT "usually busy around that time." I decided to put on hold, all other considerations for the other restaurants... I originally was making reservations for a place nearby Wash Park, but wanted something close, because hello? Work tomorrow. Also Colorado's weather was -9! We wouldn't even been able to walk anywhere and enjoy it. We parked, got a glance of the outside, super amorous, then my jaw dropped at the crazy line! Nick and I just accepted our loss, and the hostess was asking us if it's delivery/dine in. We asked for dine in, we actually got our table prioritized. Turns out the first red flag was that line of ONLY online orders. The hostess admitted they were behind schedule and it's going to be a wait. We didn't mind. We came at 7:00pm. It was 8:00pm, and the tea we ordered, completely forgotten about. The sushi didn't come until 8:30pm, the other tables just looked so upset. We were applauding to their chefs, working their tails off. My, they were busy. We got some Edamame on the house, and we got our teas replaced. After that wait, Our Monkey Brains came out and it was just... much to be desired. Tasted strange, bland and the flavors didn't compliment each other. Different flavors, but just didn't mash well. We got our 2 cups of Japanese Hot Tea, WHICH WERE COLD. They charged $5.50 for them. What a joke. The Ebi roll was the only alright roll for $2.00. The Godzilla Roll lacked of flavor, and Nick finished that one. The roll itself wasn't what I liked. The Smoked Salmon tasted stale, and tasteless. THe Alaska Roll was decent, just annoyed how late it was brought out. The 3 Avocado rolls we ordered were actually one of my only ones that I enjoyed. I don't even think they brought out our Salmon Mango Roll. We didn't even stay for dessert, and I always order dessert. This place wasn't for dessert. We ran out of there. read more
