The cozy atmosphere makes this place perfect for a night out. The Sushi was amazing and you can tell that the fish is fresh and of great quality. The servers were very friendly.

IKKAI is a true hidden gem and the best place for sushi in downtown Naperville. I tried the scallop crudo special and 109 roll. The scallop crudo had cucumber, avocado, mandarins, and yuzu sauce and was served with rice crackers. It was bright, citrusy, and the perfect starter. The 109 roll had crab, avocado, cream cheese, and was topped with baked salmon. This roll was absolutely delicious - rich, sweet, and savory. I could not have been more happy with the food. The service was fast and efficient, and the staff was very pleasant. The only qualm I have is that the lighting, especially during dinner, is really subpar. The restaurant is dark, and since we were sitting in the corner it was impossible to see our food without pulling out a flashlight. Overall, I highly recommend IKKAI, and I will definitely be back for more sushi!

Amazing sushi, very cute and small spot. Kind of hidden, you miss it sometimes while walking or driving.

Every single time I come here, I leave a better version of myself simply because this is one of my happy places that experience for me would be impossible if the vibe was not in alignment with my own Dr. Loren

I love this restaurant! One of the best sushi restaurants in Naperville. Main St and Naperville roll is one of my favorites. As well as the crab gyoza tastes like no other. The service is great and the staff is all so kind.

Solid choice for great sushi! This place never fails and sushi always tastes fresh. Small restaurant with limited seating so might want to call in advance. Retro themed props like old typewriters displayed which are sort of interesting but the food is on point!

My husband and I visited IKKAI for his 30th birthday last summer and it did not miss! Every roll we had tasted SO fresh and so delicious! We have yet to find a better sushi spot in the Midwest. We enjoyed watching the rolls being made, as the restaurant is a little smaller but it made the experience more intimate and lovely! Service was always attentive and pleasant. We had to wait a bit to be able to be seated but it was 10000% worth the wait. Plus you can always go explore around downtown Naperville and grab a drink beforehand at another spot while waiting. Definitely will come back here again!

My friend told me IKKAI was the best sushi Naperville has to offer so we stopped by yesterday for dinner with two others. It's in the newer part of downtown Naperville and definitely one of the fancier and pricier options in the area. The interior was modern and sleek, and it would definitely help to make a reservation in advance. IKKAI REGULAR W/ TUNA ROLL - 30 Each order comes with eight pieces of nigiri, a tuna roll or California roll along with house ginger salad and miso soup. The house ginger salad was OK - thought the dressing was too sour. The miso soup was too salty. I was really excited for the sushi to come out and the nigiris looked fantastic. There wasn't too much rice but the slab of fish was huge, a ratio I prefer. The tuna roll looked kind of like mini swiss rolls which was too much rice for me. The soy sauce they have here is too dark which wasn't enjoyable as a lighter and sweeter soy sauce would complement the sushi better. But the nigiris were so good!! My favorite was the piece next to the wasabi, as it was lightly seared on top with a slight glaze smeared on. All of the nigiris here were wonderful and I'd highly recommend it. Overall, 3.5/5 but will bump it to a 4/5. It's pretty expensive and I was shocked to see this pricing here in the suburbs. But the nigiris definitely made up for it.
