The only thing I like better than super good sushi is unlimited amounts of super good sushi.

While it ain't Sugarfish (LA), its pretty damn good and the service is killer. In fact, I might go so far as to say that its the best AYCE joint in the world and the fact that its located in Vegas only adds to the magic.
For $26.95 you can get some of the best sushi available in good ole Las Vegas, plus unlimited appetizers, daily specials and wait for it...DESSERT! Trust me you won't want to skip dessert because they have an amazing green tea creme brulee and s super sweet selection of mochi ice cream.
My only recommendation would be to get in early and to sit at the bar so that you have your chef's full attention. The rest will take care of itself because Goyemon does it right from start to finish.
DEFINITE MUST EAT!!!
