YUM!
It's hard to pick out a restaurant in Vegas especially since 50% of them are Wolfgang Puck. I picked this restaurant since I was super hungry and at the forum shoppes. But it turned out to be one of the best places I've been to. The staff is very polite and helpful. The atmosphere is really cool and the food is cooked perfectly to give you an taste-gasm. I would recommend the pizza. I know that pizza is not a normal choice at a fancy restaurant but it's probably the best pizza you will ever have.
The restaurant itself is not really fancy, it's more like a upscale casual and the prices aren't outrageous.
Overall, I doubt that you will be disappointed if you decide to take my advice
