If you're staying in the MGM or NYNY, this is THE place for a night time snack to make the next morning feel less bad. It's open till forever and the slices are thick, big, and the right amount of greasy. The piano bar is next door so you'll be treating to some live music with your slice. Yes it's $5 for a slice and you'll need two but it's small price to pay for convenience and feeling ok the next morning. The whole pie is a much better deal but if you can wait the 25 minutes, you probably don't need it and can get a more quality pie elsewhere :)
