Love the MGM Grand! It is sooooooooo big though and if you do not like a lot of walking then I suggest skipping this place. One time my wife and I left our room, went down the hallway (Which really should have a free monorail in it because its so damn long), got in the elevator and then realized we forgot something. Normally you just go back to your room, but after all of that we decided to get it later.
The place is full of great eats like Tom Colicchio's Craftsteak, Wolfgang Puck, Emeril, and Michael Mina's Nob Hill. But dont worry they also have Starbucks,Nathans and other cheaper eats for the budget traveler.
You will love MGM Grand if you are into big flashy Vegas style hotel and casinos. It also has the MGM Lion den, a 20,000 seat arena (which I saw 2 concerts at and it is surreal to have an arena in your hotel) and a great pool area.
