I've been to Cadillac Ranch a couple of times now. The actual restaurant and bar is very nice. It's spacious and has some nice spots to hang out with with a group. They also have a mechanical bull!!
However, the drinks I've had were not good. They just didn't taste good. The food was also lackluster.
I've never had a problem getting in or trouble at the door. I just think for the drinks and food prices, I'd rather go over to the Blue Martini literally next door during 4-8pm and pay less for better drinks.
