Moved to Las Vegas almost a year ago from Hawaii. My mom brought me to Inaka Sushi and I have to say, it's better than any sushi restaurant in Hawaii.
All you can eat is reasonably priced. They have a special "yum yum" sauce that is addicting! Selection is larger than almost all sushi restaurants I've been to in Vegas so far. And there's never a wait for a table.
The only downside I can think of is they don't serve Tobikko, but the Masago substitues just fine. Also, mochi ice cream would be a great addition to their menu.
All in all, this is really the only sushi place I like to eat at. Would recommend it to ANYONE, and will go back again.
