Stick with the Sushi

We went here for dinner as a large group last night. Sushi was very good, but the non sushi food was just ok. Tempura was cold, teriyaki steak was tough as well. Sushi a was very good though with lots of unique rolls. Waitstaff was attentive and nice. Good experience overall but stick to the sushi... read more

This isn't the typical sushi bar type of place at all, but it's still worth the visit. It has the traditional sushi items and they are fine, but the real feature of this place is the unique roll combinations. I will come back for those because they were really interesting and really good. Our server Ashley was so helpful and... More

We were dining with two children. They got full on the appetizers. The plates of the entrees were so full, we adults had to take 1/2 our meals home too. It was a delight to the palate.

There are two locations for Happy Sumo, one is in Salt lake City and here in Denver. We have frequent both locations and have never been disappointed. The Sushi is always fresh the servers are attentive Can be a bit pricy but worth it. There seaweed & Cucumber salad is a great appetizer and the rolls are large so plenty... More

I love this place and always overeat when I'm there. Beautiful atmosphere and the food is great. My husband is not a fan of sushi but we can still go there because they offer surf & turf as well. I can get what I want and so can he- best of both worlds. While I love this restaurant I don't... More

Went on a busy Friday for lunch right after school was out for the summer. Service was slow, inattentive, asked for a to go box and got tiny box kind of thrown my direction, no drink refills just generally did not seem to care. Food was poorly prepared, did not taste very good and was smothered in some sweet sauce.... 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
