So worth it! So excited this place opened. The food is great. I really loved the small plates and the noodles. The fried rice was a little soy heavy but there are so many good things there it's not a problem. This quickly became our new group dinner spot.

OH MY GOSH SOOOOO GOOD! Like, you think you've had a good all you can eat sushi experience and then you find this place. WOW. First of all, variety--amazing. With their all you can eat meal you can get dumplings, buns, wontons, chicken wings, big or small bowls of ramen, hibachi meat/veggies, rice, noodles, rice cakes, sushi, the list goes on and on. Then there's the fact that everything we tried was SO GOOD. I kept waiting for something we ordered to come out subpar but honestly I'm like when the heck can we go back I'm already craving that hibachi steak and fresh rolls again. If you love Asian food and if you love variety, this place is your roman empire. I'll also say the service was top-notch and the atmosphere is so fun--honestly reminds me of a place I'd been to in Japan. Just the pe

⭐⭐⭐⭐⭐ KOI Ramen and Sushi We’ve been watching this team pour months of care, craftsmanship, and detail into building out their restaurant, and the anticipation was real — and they absolutely delivered. The food is incredible. While there are only a handful of gluten-free and dairy-free options, they are extremely accommodating, knowledgeable, and careful. Every allergy-friendly dish we had was outstanding. Our non-allergy family members have also loved everything they’ve ordered — which says a lot. They also offer an all-you-can-eat buffet during dinner on weekdays from 4 PM to close, which has been a huge hit and definitely adds to the excitement and crowds. The staff is professional, kind, and clearly working their tails off. We are genuinely lucky to have a place like this in our co

This is currently the best Japanese restaurant I've experienced! So happy to have found such a delicious Japanese restaurant here! I've been to Japan many times, and the quality of the food here is excellent! The service is also fantastic! I will definitely come back again!

Food: We tried the AYCE menu and I ordered a few appetizers. The seaweed salad and takoyaki were high quality and had a good flavor. Some of the others (like the egg rolls and wontons) had a cheap feel & flavor to them, which is expected I guess at AYCE places, though. All of the sushi rolls I tried I enjoyed a lot and they were all good quality. The fish was fresh, the sauces were good, and they had a pretty presentation. All of the flavor combinations were delicious, too, with some notable ones being the mango tango and Hawaii rolls. Service: Everyone was welcoming and kind. There were a few kinks in the service, though, such as several waiters asking to take our orders or asking if we had this roll that someone else ordered. I understand it’s opening week however and I won’t ding them
