Sakana is the the bomb. Good service, great AYCE menu, cool dining atmosphere complete with banging tunes. Although the maki rolls ain't anything to shake a stick at, the nigiri is much more memorable. If you're visiting Vegas from a part of the world lacking a strong sushi offering, dedicate your precious gastric space to the nigiri. After having visited Sakana in the past, they seem to have gotten even better over time in terms of both food and service.
