We recently moved to the area after living near Mitsuwa in Arlington Heights, and have been missing sushi. Since it's mid-pandemic as I write this review, I've only been able to use their takeout option, but it's been absolutely delicious and hope to visit the dining area in the future!
The staff here is very friendly and knowledgeable about gluten allergies. Our family has Celiac's dietary restrictions, and Kumi Sushi has done a great job in food handling for our requests. Highly recommended!
