It's a 24 hour food court pizzeria but I'm rounding up to 4 stars because it's the cheapest option in Venetian and the staff is friendly.
I wish I had taken a picture of the grease. I literally had to use 6-8 napkins per slice to get even some of the grease off the top of the slice. It was great drunk food though.
The prices on the ready made (assorted) pizza slices are reasonable $5-$6 range. The slice filled me up for at least half the day.
Lots of restaurants in Venetian are over hyped so if you just want something cheap grab a slice here and save your money for gambling.
