Worth the drive from Loveland for lunch. Food is amazing as well as the service. Even with the Habachi lunch menu theres still plenty left over to take home.

Very fun, fresh sushi, can be a little pricey but worth it for the quality. Also, they have great lunch specials at a reasonable price. Staff is always very accommodating, and the atmosphere is modern and comfortable. Their dim sum is amazing, but I think being discontinued soon. Great for a date night, solo meal, or with a group.

Sumo is our goto sushi restaurant in Boulder county. The food alone is worth your time but the service is quick and friendly and the atmosphere is modern and comfortable. Go eat their fish, youll be happy you did.

Sumo is one of the best Ramen and sushi restaurants in town. The service, especially Regina, is incredible. My pregnant wife said the bento box lunch special was the perfect amount of food. Management was phenomenal and answered all our dietary questions. It is a must try for a quick lunch. Even the togo bags are nice!
