Met an old business associate for lunch. About 25 minutes outside of downtown Denver. Large menu for sushi but also had selections of "cooked" food... Split appetizers, around 4 and it was more than enough for two people. Not too thrilled with the lettuce wraps, but loved the edamame and potstickers. Didn't drink alcohol but they had a full bar...

We had tried to go here on previously but it gets crowded on weekends. Walked right in a Sunday night though. They have a huge range of creative sushi rolls, service was prompt and pleasant. Everything we tried was tasty, the place is nicely decorated and a welcome dab of hipness in suburban north Denver.

Made reservations for our family on a busy Saturday night for a special occasion. Had never been before & read mixed reviews. Sumo sampler was delightful. Good wine, cocktails and saki. The special rolls and signature rolls were unique and oh so good! The food, service, and ambiance exceeded my high expectations. We left full and happy!

It was a really great experience. Me and my husband enjoyed the food very much. However, the service was acceptable but it could be better comparing with the price we paid. Will be back for sure but this is not the restaurant for every day dining. It is a little pricy but worth for special occasion.

Service, food and drinks vary...not consistent .Drinks and dishes are never the same, guess it depends on who is working. We usually go on VIP nights to save money.

The worst sushi we've ever had anywhere. The service was horrible. They couldn't even provide hot tea. It was expensive. The fish was old and smelly.

As soon as I walked in the door, I saw two waitresses just speaking to each other not attending to me at all for at least 3 minutes. They didn't even say hello. When I got seated by Ashley, she was nice at first, but then I had to ask her to refill my water. Then another time when I... More

The fun looking atmosphere took us in, but...This is an upscale restaurant for the area. We enjoyed their sushi, and enjoy different types, styles, and cooking of food. We were hoping for a new place to go, but felt it was too high priced for the area, and my husband and our daughter got sick on the seaweed salads. My... More

A great sushi restaurant in an unexpected place -- for some reason I don't expect to find great sushi in a mall restaurant, but this place was recommended to us and was absolutely wonderful. The sushi was imaginative (I had something with salmon and cream cheese inside and crab on the top -- amazing). Everything we had was wonderful, and... More

My husband and I tried out this restaurant for our 9th wedding anniversary. The atmosphere is modern and sexy. Upon arrival we saw tables and U shaped booths. I think that night they were understaffed, because we requested a booth and we were denied seating due to the fact that they were not "ready" for seating. However, they were cleaned... More
