There is a coupon for Strictly Prime Rib (2nd floor next to the mexican restaurant at South Point) where you can get one meal comped. I had a steak...my wife had liver and it was very, very good. They also had a wine special where we got a bottom of Santa Ema Merlot for $20...good wine/good value.
In addition, you can get $2 tequilia drinks (anything from Patron or name it) at the bar right outside the restaurant. If you do go to the mexican restaurant, be sure to grab a couple marquritas to take in with you which is perfectly OK to do.
