Outstanding appetizers, sushi, and the service was prompt, friendly and accurate!! Great atmosphere!

Excellent all around! Great in house dining and fabulous take out! Sushi is delicious. Thank you, thank you!

I've never had a bad experience at koi, both dine and for take out. They have a wide variety of sushi choice and the flavor and freshness can't be beat in this area. Service is always top notch and they always treat my young son with kindness and patience. Located right in downtown westerly, it's a perfect stop!

Sushi was delish and presentation was great! Service efficient and ambiance chill. Sake nice and hot! No wait and plenty of seating:)

Excellent food! Sushi is served timely and courteously with wonderful service! The restaurant is a wonderful place to sit down and relax. Highly recommend!

Koi restaurant is a perfect spot when you are craving sushi, scorpion bowl, and a seafood veggie bento box (not necessarily in that order).

Pretty good Japanese restaurant on Westerly's High St. It was a quiet day for lunch, just a few locals popping in for a bite and a drink, and so we had a restful and restorative meal. Service was prompt and polite. The sushi and sashimi were very good, nicely presented, and fresh. My wife's salmon teriyaki was well prepared and the accompanying fried rice was outstanding. My tempura nabi was tasty and hot, with thick slippery udon noodles, a clean-tasting broth, and a pair of crisp tempura ebi. A satisfying meal!

Saw this restaurant as we were walking down the street and decided to give it a try. We had a very interesting roll that had banana and tuna. I greatly enjoyed it. We also had the basic California roll. The hibachi chicken was more like a fajita. It was served on a bed of onions which I found strange. We sat at the bar and had excellent service.

Come on Yelpers, 4.5 stars for Koi? It's hardly an impressive venue, that is until you start eating the food, which in my opinion merited 5 stars on both occasions. We opted for takeout, and candidly thought the food here was great! My co-diner said Koi's shumai was the best she's ever had and ordered it twice. We also tried the gyoza, fried rice, and sake don (salmon), miso soup and house salad. The sake don was excellent, a substantial portion of salmon sashimi, served over tasty rice, accompanied by nicely prepared miso soup, and a small house salad. The house salad was mainly lettuce, but the dressing was nicely done. Our orders were ready on time, nicely packaged and ready to go. We ate our dinners in the beautiful Wilcox Park, which is essentially behind the restaurant, and offers fountains, a large fishpond, perennial gardens, lovely paths, and mature trees. It's a gem of a little park which is adjacent to the library. If we lived in the area, Koi would be our go to place for sure!

After an evening of drinking wine we walked down the street to Koi. It was later in the evening so it wasn't busy at all and the service was really quick! Started with a Shrimp Tempura roll. A little on the smaller side than what we are accustomed to getting, but it was very good. I had the Shrimp and Chicken Hibachi that was served with Hibachi Soup, Salad and Fried Rice. Also had a side of Noodles because I just had to! Lol. Everything was very tasty!
