    Dinosaur Eggs
    Joanna M.

    For sushi, Sushi Koya is very affordable given that the sushi is sizable and great quality. My partner and I walked in and were immediately seated. The vibe was calm and relaxed when we were there. My partner and I ordered the Dinosaur Eggs, the Salmon Lover Roll, and the Volcano Roll. Our server was friendly and efficient and took our orders in no time. The Dinosaur Eggs were true to their name because they were big. Taste-wise, they were pretty good but nothing special. The Salmon Lover Roll was our favorite and the mango in the middle didn't overpower the salmon (I find some salmon mango rolls to be too sweet). The Volcano Roll was also decent but nothing special. The fish for all the dishes were fresh though and the portions were great. If you don't wanna pay the price for a special roll, Sushi Koya also has Maki Mondays starting 8pm and you can get tons of maki rolls for cheap. So if you wanna get Sushi at Mohegan Sun, it's definitely worth it.

    First time Diner and I'm so glad I switched my previous reservation to this establishment. There is not enough reviews for this location to signify how amazingly fresh and tasty this food is. Staff is so friendly and food comes out fast and so flavorful. The ambiance is small but cute loving the ecstatics with the deco art. The food is deliciously tasty and just soo freaking fresh. It was definitely made with a lot of love and we will be back again....

    Decent, contemporary if eclectic collection of unconventional sushi, with a wide array of American and other influences, e.g. clam chowder. A bit pricey but definitely one of the better venues at the casino, and fairly large in portions. Good for any party or occasion. Food is decent but not exceptional.

    Martini Bowl
    Iva S.

    I enjoyed my quick sushi dinner. Staff was friendly. Food was delicious. I ordered the edamame and Martini Bowl. Didn't take a whole lot of pictures because i was having a great conversation with another guest that sat at the sushi bar next to me. Great place for singles, couples and families. Call bar and dining areas. Self seating. First come, first serve.

    Christmas roll
    Nicholas H.

    This is a small restaurant that doesn't take reservations, but we were lucky to go on a quiet day. The service was friendly and the food was fast. The menu seemed pretty limited, but it is a small restaurant so they do a lot with what they've got. We ordered the high roller (with a Little Tokyo roll) and a Christmas roll. The Christmas roll was quite good, but we had a few issues with the high roller plate. The Little Tokyo roll has a lot of ingredients, but the menu didn't list spicy sauce as one of them, and unfortunately it was there like the guest you didn't invite to your party but they show up anyways. Even without it, the other issue was that everything blended into one generic flavor with no real standout. I'd have to recommend getting a more focused roll if you're looking for one flavor or another, it's a real shame to have so many great ingredients but not really the taste of any of them. The other issue was the shrinkflation present in the nigiri portions. The slices were very thin, so while they plated 10 pieces, they were each half pieces, so it was 5 normal size nigiri. Would I say what we got was worth $160? Absolutely not. In good news, they have a military discount. This is not the best sushi at not the best prices, but if it's Tuesday and the best place is closed, this isn't horrible.

    Oyster with amazing clam?
    Ma S.

    Haven't done a review for 2-3 years, lost my Yelp Elite status, lol. This place is right next the hotel lobby, used to be a coffee shop that I go to, sad. But I am glad it's Sushi, the only Sushi place at the Casino, can't complain too much. The oyster was good but the Clam was amazing, freshest! Got the Sushi appetizer which was good but nothing to write home about, might have been pre-made sitting in ice? Given that the fish doesn't look shiny. but it's a much better deal at $12 than the Sushi regular ($28 for 7 ). The American dream roll was very complex & tasty with soft shell crab, but one piece had crab that tasted a bit fishy. This was with beer, without beer, it might have been more fishy? Overall good, a bit pricy as expected.

    Dragon balls or dragon eggs. Forgot the name. Delicious though.
    Linda S.

    Came here on a Saturday evening and got lucky to be seated right away. To our surprise, their food was delicious! Why do they have to be so far? Their sashimi was so fresh and the toro was amazing. Presentation of the food was so cute and pretty. Even their wings were good. (I always order wings no matter what). Definitely will go back.

    Delicious sushi spot located inside the Mohegan Sun casino in Connecticut. Perfect spot for a lunch/quick bite , it's cozy and the fish was fresh. The server was attentive and everyone I interacted with was helpful. The music was lively, which I liked ( top 40's playlist) their drinks were super yummy and they presented it well. My mai tai was served in a coconut. I would recommend popping in if you're in the area Con: no bathroom in the restaurant, you have to pop into the next restaurant to find a toilet

    dragon egg - delicious
    Marissa S.

    really good sushi! i was definitely impressed with the food! would give 4.5 if i could because i didn't love the ambiance, though it's totally fine. i had a special salmon roll and alaska roll - both had fresh sushi and were very good. husband ordered a dragon egg and that was my favorite dish. i'd definitely order that if i come back.

    The jackpot

    Pretty good food and value. It was crowded so service is a little slow but the waitress is friendly. We sat at the bar and it is fun to watch the chefs make the sushi.

    Helga S.

    Upscale sushi-ya at the casino, pricey novelty sushis & rolls, sushi donut, anyone? Was immediately seated at sushi bar and prompt water service. Waiter was attentive and food came out quickly. Appetizers are typical for a sushi restaurant, crazy maki rolls & novelty sushi, sashimi menu items. Ordered the martini glass, 6 different sashimi served in a martini glass or large spoon, in my case. Was intrigued by the sushi donut, hard to eat unless to pick the whole thing up and bite. It was ok. Restaurant was pretty busy, every table filled and baseball game on the tv. It was an ok experience.

    Dragon eggs. Delicious.
    David R.

    The dinosaur eggs were great and the sushi was very good. They don't take reservations but the wait wasn't long.

    Salmon Sushi Donut

    Visited for lunch on Sunday. Our server, David, was excellent! My daughter really wanted to try a sushi donut, but she's not a fan of spice, which they all seemed to include. Luckily, maybe because it was slow, but it seemed to be absolutely not an issue, so she ordered the Salmon Sushi donut (not spicy) $20. What came (see photo) was so fun, absolutely fresh and so delicious. She was overjoyed and there was a ton of fresh fish both inside and out. I ordered the Christmas roll ($21) and it did not disappoint! I think it's now my favorite sushi roll ever! I'm still thinking about it and I know not every sushi place makes them and they're certainly not up to par with the freshness of this one! Yes, it's expensive. You are at a casino in Connecticut. But, they filled us up enough to last until dinner time and we were so happy and fulfilled. David was a great server, the place is beautiful, clean and it's always fun watching the chefs prepare items. Thanks for a great lunch!

    My wife and I were staying at the Madison Beach hotel a few days prior to our best friends…read moredaughters wedding * New Haven Pizza of course was on our radar, but after a full day Lobster crawl we decided that sushi would be the perfect follow up for dinner. So after reading numerous great reviews we chose to dine at Mesa Sushi in nearby Clinton. From the moment we walked in, the hospitality was genuine, attentive, and effortlessly warm--striking that perfect balance between professionalism and personal care that truly elevates an evening. The quality of the fish was outstanding. Every piece was fresh and beautifully presented, You can usually tell when care goes into sourcing each ingredient especially when it comes to sushi. The entire experience felt upscale yet welcoming, making it a standout not just in the area, but anywhere. We look forward to returning and would highly recommend it to anyone seeking an great sushi experience.

At our last visit, the bar man was engaging in a loud unpleasant political conversation with a patron. Tonight, waitstaff were engaged in a long chat with a customer right next to us. Both experiences left me feeling there are no boundaries for waitstaff chatting with diners. If you want a private dinner where waitstaff are professional, this may not be a good choice.

As I drive up to it I got a little concerned as all the parking spots in front were taken. Almost moved on until we saw they had a parking lot off to the side. Pulled in and went inside. We were seated right away after given a few choices of where to dine: hibachi table, booth in bar area or booth in dining area. We chose the dining area which happened to be right next to the hibachi tables so we heard the chef over there as they cooked. They use only one menu which seemed like it was their takeout menu. No real complaints I guess as it did list everything. Our appetizers came out quick and food was good. Although the steak bits seemed a little dry. Liked that they allowed us to swap out the mushroom soup with miso soup. Salad was good, they used a different Asian styled dressing which was tasty. Portions were large and we wound up taking some leftovers home. Took close up menu pics as the ones in this site were hard to read. 4 stars because we kept being visited by a couple pesky flies around our food.

Typically find these tasting flammable but this was the perfect balance and probably could've had several. Our server was super nice, food came promptly, overall a good visit.

It was a bit above average for the area and prices were better than I've seen elsewhere. My husband and I dined in on a Saturday around 6 pm. The place was already slammed with online orders and it did not stop the entire hour or so we spent in the building. Everything is disposable even when dining in and eating out of styrofoam isn't my preference but ok. It's a small establishment and I would guess the overwhelming majority of their business comes through online ordering. So, order online rather than go in as there is no real ambiance. I tend to order pretty basic rolls and sashimi which I think really levels the playing field when it comes to sushi. So, my commentary on the sushi is just based on the quality of the fish. It was alright not particularly vibrant or fresh. But not bad either. The pieces of sashimi were literally the biggest I've ever seen. They were too big to comfortably one-bite. The spicy tuna roll was pretty good and didn't require soy sauce to make it palatable. The miso soup was also good. My husband loved their salad dressing. If we decide to order again I would skip the sashimi and probably order some à la cart nigiri to form my final opinion. The search for a truly killer sushi place around here continues.
