If you're into gambling more seriously than wasting $50 at Bellagio, I think I have to suggest Circus Circus. My game is blackjack and they're the largest casino with the lowest minium, normal rules, and most tables deal out of a shoe still. $5 miniumums on a straight game of blackjack is tough to beat.

The clientele at Circus is mostly white trash, but they're fun to play with. There are tables with sucker bets, but they're all optional (unlike some places downtown).
