    I came to IKKAI on memorial day weekend on a Sunday with two friends for lunch. It was surprisingly not too busy and we were able to be seated immediately. We were able to order from the dinner menu when we visited. Note: Outside drinks are not allowed -- but the staff stored our drinks in the fridge as we ate. We ordered the Ikkai Sashimi ($40), the Main Street Roll ($13) and the Sake don ($35). The Sashimi and Sake don came with a salad and miso soup which were decent. The Sashimi was overall good and plated beautifully, although the cuts were smaller than average. There were two different kinds of salmon -- my guess is salmon and ora salmon. The ora salmon (fattier) tasted especially fishy, as if it wasn't super fresh; however, everything else was great. The sake don came with a lot of pieces of salmon and some baked salmon with mayo on the side, which was a nice surprise. My friend said that the main street roll was the best crab roll she has ever tried (she loves crab). Overall, I would say that the value of what we ordered was not bad. The taste of the sushi was also good for the area. The portions are definitely smaller, but the presentation was definitely a nice touch. I will definitely return to try other dishes in the future!

    Whenever I’m craving really good sushi, this is my go-to spot—they never disappoint! The ingredients are always incredibly fresh, and everything is bursting with flavor. It’s consistently delicious and clearly made with care. The only downside is the limited seating, which can make it hard to get a table sometimes. But honestly, that just speaks to how popular and amazing this place is. Highly recommend it to any sushi lover!

    A true Naperville gem and must try if you love sushi! The restaurant is small/intimate but very welcoming and the staff is very kind and knowledgeable. You can’t go wrong with the Hangry and the Zesty Salmon rolls.

    Hands down the best sushi I have ever had and I have tried lots of places. Everything was fresh, tasted amazing and was just as advertised. Daily specials and monthly specials available. The servers will tell you all about them. Definitely try everything crab that they have. Second best would probably be the salmon options. Also great drink options. Ask for recommendations since the servers are really helpful and nice. Tell them about celebrations or special occasions ahead of time as they can use some of their magic to make it even more special. It says online that they don’t take reservations but we were told that one of the table was reserved so maybe call and ask. We were lucky to get a table right away and then 15 after us there was already a line with an hour wait time. They have a handful of tables and some bar seating but it is a small place so keep that in mind. It’s downtown Naperville so parking is a hit or miss depending on the time and day you are planning on going. They get busy in the evenings and weekends are probably even busier. Awesome place!

    Absolutely thrilled with this place! The sushi was incredibly fresh, every dish full of flavor, and the staff was very kind and welcoming. I tried the Uni Toro Nigiri with caviar for the first time - pure perfection! I also loved the atmosphere - dim lighting, cozy candles, and that hidden, almost secret vibe that makes the place so special. Cozy, elegant, and unforgettable - can’t wait to come back!

    Hands down best sushi I have ever had. It was fresh, tasty, and personal. Jay the owner is behind the sushi bar working hard right along side his team, but makes time to have fun and connect with his guest. The small intimate location is right up my ally but does come with a wait which is the only downside so come early or plan to have some free time. Plenty of things to do near by so this isn’t really a concern but if you don’t like to wait keep that in mind. Can’t say enough great things, can’t wait to go back. New favorite sushi.

    A hidden gem. The space is absolutely incredible, a small but welcoming environment. Sushi… out of this world. Every single item was remarkably fresh and delicious. The staff must also be recnogized here - every single employee was so kind, welcoming, and provided great insight on the menu options. Manny was an absolute gem, giving great recommendations and checking in. Her warmth and positivity bring a good energy to the space!
