Came here 3/4 nights that I was in Vegas for Halloween weekend. It's the best thing when you're drunk at three in the morning!
I got cheese pizza one day and pepperoni the others. Straight out of the oven it's delicious, but also as good the next day! Their garlic knot things are okay, not too much garlic flavor. I guess something to soak up the booze.
It's located in the food court the bottom of the MGM Grand Hotel. It's the only thing open there at that hour bedsides McDonald's. Super friendly staff even when dealing with drunkies. I'll definitely be back whenever I stay here.
