Avoid! Bite the bullet and walk over to MGM where you can find food that is (a) not crazy expensive and (b) not totally disgusting.
I had the cheese pizza, and a diet Coke. Grand total? Around $18. $4 for a tiny diet Coke, no refills. The pizza would be big enough for two people...if those two people weren't hungry.
The pizza itself was disgusting. It had WAY too much cheese. And, I know, you're going to say "impossible! I love pizza with too much cheese." No. Seriously. I scraped off a bunch of the cheese, and brought it back to the room, and even then people who swore there was no such thing as too much cheese were disgusted by this pizza.
The rest of the bachelorette party group wanted to go there later on, and I insisted we should not go there. It is a totally gross rip-off (and this is even by everything-is-a-rip-off-in-Vegas standards).
