Project Pie is a great, reasonably priced and fast alternative to the higher end sit down restaurants in the MGM Grand. Sometimes you just want a quick bite that's better quality than fast food but not as pricey or slow as a sit down restaurant.
It is conveniently located near the lobby and Porte cochere, just down the escalator to the walkway to the monorail.
I had a sausage and pepperoni pizza and it was very good although just a bit greasy. Less than 10 mins from placing my order tip I got my pizza. The size was about right for a small meal but don't expect to fill a huge appetite here.
I'd definitely return.
