I'm mainly writing a review for Monday Night Football here. For $20, you get 3 drink tickets, free food and a few raffle tickets. During every commercial break, they draw tickets where you can win prizes such as lap dance dollars, t-shirts and a usually 1-2 bigger prizes like a bicycle or a stereo for your home. During half-time they have $1 lap dances where u get a bunch of girls come around and give you short 10 seconds dances for $1. Overall, it's a great time and I've taken friends who don't really have in interest in NFL and they really enjoyed.
I also suggest that you stop by the Las Vegas Hilton before and make a few proposition bets. They don't have to be high bets. Just make like 3-4 and everyone chips in $5 for each bet. It makes the game a lot more fun when you're rooting for sacks, INT's, etc. Especially when it's 2 teams that you don't really care about.
