The first time we went 2 years ago we went for dinner. I love that they have Shiner Bock - not a lot of places do. I had the pulled pork which is my sandwich of choice that I base places on and the BBQ sauce was amazing - I bought a bottle before we left. My husband had the chicken fried steak and loved it also.
The second time we went last year, we showed up when they opened at 11am, grabbed a barstool, and left at 5pm. We had met up with friends of mine from high school that I hadn't seen since high school (16 years!). The bartenders were awesome for the whole 6 hours, and as much as I loathe domestic brews, the 2 for 1 specials allowed us to have a low tab and be sufficiently drunk. I love all the free shots when they play the signature song, too! I still had plenty of Shiner Bocks and a few mixed drinks and a few shots of Jager along with a plate of nachos and we left there with a bill of $45. I can't wait til the next time we're in Vegas to spend some more time there.
It's very convenient to get to from the monorail, but pretty far back in Harrah's off the strip. Still worth the effort.
