Koi Japanese Steakhouse & Sushi
About This Spot
Stepping into Koi Japanese Steakhouse & Sushi in Lewiston feels like entering a place where every visit carries a measure of warmth and celebration. The moment you arrive on Main Street, you’re met with an inviting blend of energy and comfort, where the buzz of the hibachi grills and the quiet charm of the dining room coexist under one roof. It’s a restaurant that embraces both the lively, interactive theater of hibachi cooking and the calm, focused enjoyment of thoughtfully prepared sushi.
The ambience here shifts gently depending on where you choose to sit. At the hibachi tables, the pace is spirited and communal, filled with laughter and the captivating dance of knives and flames. It’s a space designed for shared moments, whether marking birthdays, special gatherings, or simply indulging in a fun night out with friends. Just steps away, the sushi bar and dining area offer a more subdued rhythm, where conversation flows alongside meticulously crafted rolls and delicate flavors that encourage a quieter, more reflective dining experience.
What makes Koi feel distinct isn’t just the food itself but the human moments woven through the visit: servers who strike a balance of attentiveness and lightheartedness, couples and families finding their own comfortable rhythms, and chefs who bring an artful touch to both traditional and creative Japanese dishes. The menu invites discovery — from spicy edamame and hearty teppanyaki plates to inventive rolls that playfully blend familiar ingredients with unexpected twists.
This is a place where a night out might mean an energetic hibachi feast full of sizzling theatrics, or a more intimate meal centered around the subtle flavors of fresh sushi. Over time, many local diners have found themselves returning for those quiet celebratory moments as much as the lively communal ones, drawn back by the sincere hospitality and a space that feels distinctly theirs.

Took my husband here for his birthday on the hibachi side it was a fun experience. Service and food was great. The only mild complaint is that we where a bit cramped at our grill. But it was still fun. We also love the restaurant side. It's quieter, the service is good, and the food, especially the sushi, is great. We now come here for all birthdays, and just because dates. There is occasionally a wait but it is not bad. However, I do call ahead when I know we're going to have a big group.

It was super loud. We went just for the food n dining not hibachi but the hibachi area was so loud it made the dining experience not good. They were very entertaining n the guests in that side was enjoying for sure but there has to be some consideration for other people who want to enjoy a more relaxed environment. Food n service was good otherwise. Maybe a door?

The Habachi Grill was an excellent choice. Our group of 6 paired with a group of 5 and it was great. The server was funny and talented and the food was very good. Our group had a variety to cook, filet mignon, chicken, shrimp, and salmon. All was delicious.

Been here too many times now and have enjoyed every experience. Last time, the servers Kresna and Zee were so funny and nice. We had Kevin tonight and he was very accommodating to our sushi tastes. Koi has a good mix of traditional sushi and creative rolls, like the Koi special banana roll. Anyway, would recommend 9.5/10.New update: Kevin just gave us 2 mini strawberry desserts adorable! They have a new point system so make sure to sign up!

the food here was so delicious!! everyone was very kind, and food was served quickly, I got the lunch hibachi which was priced at only $13, great price for fresh hibachi!

This place is quite the gem! I was met quickly and sat down instantly. I ordered the Steak and Chicken Hibachi combo but not at the Hibachi table. Nonetheless, the food was fantastic! I also ended up ordering the Fried Cheesecake which isn't actually called that, I'm unsure what it was but I know it starts with a Z. It was the best tasting way I've ever had cheesecake. This place deserves all the business it gets and more. Everybody was nice and multiple people came and checked on us. I would totally go back if I lived in the area still.

Service is amazing and all the fish tasted as if it were caught the day of. Flavor of everything was awesome. PLEASE come here and if you haven’t tried sushi or even raw fish TRY IT HERE!!! P.s At least ONCE let the chef make you an original role!!! They’ll do it and it turns out AMAZING

I’ve been to Koi several times now and always have a great experience. The staff is extremely attentive and go out of their way to serve customers. The hibachi experience is fun and interactive, unlike anything else in our area. The prices are SO reasonable for the amount of food you get, i never go home without leftovers. All around it’s a great addition to our valley.
