Koi Sushi

I had an amazing experience at this sushi restaurant! The presentation was absolutely beautiful — every piece looked like a work of art. The fish was incredibly fresh, tender, and full of flavor. You can really tell the chef pays attention to every detail. The sushi rolls were perfectly balanced, with fresh ingredients and delicious sauces that didn’t overpower the natural taste of the fish. I especially loved the creative toppings and the high-quality cuts of sashimi. The atmosphere was clean and elegant, and the service was friendly and professional. Overall, this was one of the best sushi experiences I’ve had. I will definitely come back again!

We are so excited to have Koi Sushi open up in Gaithersburg! It feels great to finally have a new sushi spot in the area with such a diverse menu. We ordered the Crispy Rice sushi, the Koi Roll, and the Maryland Roll, which were all fantastic. The absolute standout for us, however, was the Princess Roll—definitely our favorite! The dining room was running a little cold, but the genuine warmth of the hospitality and service completely made up for it. Highly recommended!

Koi Sushi in Rio is an incredible new addition! We ordered the Sashimi and the Emperor Roll — both were 10/10. The sashimi was beautifully presented and incredibly fresh, and the Emperor Roll was perfectly balanced with amazing flavor in every bite. My cocktail, the Ube Passionfruit Tequila Brûlée, was absolutely stellar — creative, smooth, and just the right amount of sweet. Everything from the presentation to the quality was top-notch. Highly recommend and we will definitely be returning! 🍣🍸

So freaking delicious!! Everything was wonderfull. Maggie and staff are very fast and efficient. The sushi hand rolls are 4 or 6 depending on the roll. And the chef's special rolls are 10 peices and are absolutely delicious! We had more then I took pictures of b.c. it was easy to forget I wanted to share them here. The house saki was served hot and it blended perfectly with the rest of the dishes we ate. Thank you so much and can't wait to come back!!!

We had a beautiful experience at Koi Sushi, especially getting to visit during their opening days (this was their 4th day). Everything we ordered was fresh, flavorful, and perfectly prepared. For appetizers, we had the shrimp tempura and a California roll both were delicious and a great start to the meal. The gyoza pork was honestly a 10/10, so tender and full of flavor. For our main dish, we ordered the chicken teriyaki, and it was another 10/10 perfectly cooked and absolutely satisfying. The atmosphere was lovely, the food exceeded our expectations, and we’ll definitely be coming back. Highly recommend!
