My favorite deal has to be the $10 all you can drink at the Silverton.

Or head downtown to Tributepalooza for $30

Regardless I think its safe to say all of those places will have fierce crowds. Monte Carlo terrace for $30? Sounds decent but how many people are out there and how big is the line to get to the bar? I'm guessing you'll be lucky to get the bar 3 times over the course of the evening.
