I would strongly avoid the LAS airport CPK - even if you're a CPK fan! First off, this restaurant is not like "normal" CPKs. The menu is different and the food is different. I got the Hawaiian pizza and I'm pretty sure it was not only smaller but used different ingredients and/or different preparation as well. It just didn't taste the same as what I've had at CPK before.
Second, service is awful and I'm concerned about hygiene and food safety issues. My coworker avoids dairy products due to allergies so asked for one of the salads minus the mayo. The salad came out with mayo anyway, which my coworker found out after poking at the salad with her fork. When we notified the waiter, he at first acted like there wasn't mayo on it; my coworker again poked at the salad with her fork to show the waiter the mayo, and the waiter had a huge attitude about it and let out an exasperated sigh before taking the dish away.
The waiter checked something in the system and no more than 30 seconds after he'd removed the salad from our table, delivered it to another table! I couldn't believe it. It's bad enough that the restaurant would redeliver a dish that the waiter had already put out on another table, but to actually redeliver one that he had seen my friend use her fork in! My friend hadn't actually eaten any of the salad or ever put the fork in her mouth - but the waiter sure didn't know that!
I flagged down another waiter to complain to a manager, but none came before we had to leave to go catch our delayed flight. I don't know if the waiter just ignored us or the management just doesn't care. Based on my experience here though, I'd have to wager it's the latter.
