Casino Royale is a great place to get drunk and gamble; the $1 blackjack table is right next to the bar, and the waitresses make frequent laps. (If you have your head out of your ass, it will take you forever to lose much money playing $1 BJ.)
I’m going next week, and I might actually shell out the change to see Mystere this time if the cash is flowing right. I’m told it’s fantastic. I saw the Tournament of Kings at the Excalibur last time, which was fun in a WWF-meets-Renaissance-Faire kinda way.
PS: For some more serious blackjack, I suggest the single-deck games ($5, usually) at Slots-A-Fun, in front of Circus Circus.
