The Viva Las Vegas roll was was harder and less flavorful than similar rolls from other sushi restaurants. We weren't served any ginger or wasabi with our sushi. After asking, we still waited several minutes (until all of one roll was gone) to receive a little dab for two rolls.
We dined during happy hour. For the portion and quality of food, it was definitely overpriced. I would be extremely unhappy paying the full price (which I estimate would be $75 for 2 people). Also, I think of happy hour pricing as being better than $1 off $8 drinks.
The spicy shrimp roll was good. The overall size of the rolls seemed a little smaller than usual. Not a lot, like maybe 15-20% smaller. The fried banana with Kahlua is affordable ($5.75) and decent tasting, but it honestly was about 1/3 of a banana.
The aesthetics were pleasing, but it was Very loud. They were playing "club" music, which seemed weird for the neighborhood.
