Great upbeat atmosphere, delicious sushi rolls

Love this place with friends, great service EVERY time and the sushi rolls are consistently good. The menu does not often change so its a nice place to find some favorites. Personally, the turtle shells, rainbow crunch roll or the baja roll. The white lotus from the bar is a perfect... read more

Had dinner here for the 2nd time in about 2 months. Sushi is good, not overly spectacular, but decent. Service was a bit slow, but she was really busy. Drinks were solid as well. My wife enjoys their pear martini. One of the rolls (spider) didn't taste nor smell right and they immediately took it off the bill. Appreciated as... More

We have been to this location many times as well as the one in SLC at the Gateway Mall. We always have had very friendly servers, and never much of a wait. The Vegas roll is our favorite thing to order along with edamame, gyoza & panko crusted chicken dish. They also have a very good email club offering specials... More

The Happy Sumo makes me... well, HAPPY! Their tuna literally melts in your mouth, the food is always on point and the best thing to do for yourself is to join their VIP. With the VIP (free, by the way) you get special discounts on selected days of the month. Sushi at half price, can't beat that! I have experienced... More

The service was horrible! I seated and no one came to me for at least 15min. When I was served the waitress was kinda snippy and unpleasant. And the sushi is not good at all. The nigiri rice is dry and flavorless, the fish also totally devoid of flavor, and the rolls were on par with grocery store sushi. I... More

While the food is good, the service and hostess has always been snobby and uncaring if you are there or not. Try Go Fish on 136th.

We're so lucky out here in the hinterlands to have such a fine Japanese restaurant. The tempura and teriyaki is great, and their sushi selection is incredible. All served in a fun and beautiful atmosphere with a great wait staff. Great selection of Japanese beers. Reasonable pricing and varied menu makes a trip here really worth it.

Like the title says... The portions and flavor were good, and the atmosphere was nice. We were there for lunch, and I think it's more of a dinner place. It was overpriced. And the waitress didn't have a clue about anything on the menu. When we had questions about a dish, she would just take our menu, and read the... More

I am not a sushi fan and didn't have that here. I had one of the.combo plates with the soup, salad, tempura shrimp and teriyaki chicken and steam rice and avocado roll. Let's start with the salad...no good, the dressing was salty and the leaves where dirty, the soup broth wasn't bad, the rice was good, the chicken could of... More

If you enjoy deep fried, tasteless supermarket like sushi this is the place for you. The rolls were dried and had no flavor. The rice was old, dried, and over cooked. everything was terrible, not to mentioned the fish was died in food coloring to look new. Do not waste your money and time. By the way there is a... More
