If I could give Kabuto 10 stars, I would. We elected to have the Omakase menu and went with the big boy ($120 per person). I have had sushi all over the world, and this may be the best I have ever had. The definitely specialize in the Blue Fin tuna, and don't have a huge variety. However, the Toro that they serve was just out of this world. There are a few different varieties, and you get to have a lot of it.
I won't elaborate that much more, since you don't really get a choice when ordering there. It's all Omakase menu, and you just choose between 3 different prices. This is the best meal I have had in Vegas (after working in Vegas for 6+ months). I can hardly wait to return (hopefully soon!!).
