I loooove Fat Tuesdays!
Probably the only place in Vegas you can get a sweet buzz on 2 drinks for under $20 (even when you do an "add shot")
The one in Caesar's Forum Shops has the Red Bull and Vodka one, which is my favorite. They all used to carry that flavor but then stopped.
Anytime I have people in town, Fat Tuesday is our first stop of the day or night...
