I've been to at least 5 different places in Vegas when the craving for sushi hits me, and I must say Little Buddah is my favorite. It has a nice atmosphere, a pleasant staff, and most importantly a great fresh selection.
My boyfriend and I splurged a bit on our second visit, and it was worth every penny. The big standout was the white fish (halibut) sushi. It's everything you want when you are craving sushi. Fresh with that hint of wasabi burn. Just writting this hasme craving it all over again.
All in all the pricing is reasonable, the staff is friendly, and I hope they can get some more people in the door because I plan on being a regular.
