There are better options in the CLT airport but this is at least pizza if you're not looking for the S'Barro slices.
Prices are high but aligned with what most people would expect in an airport. The choices are limited, because they can't really have much for knives here. Staff are just punching clocks.
I had a barbecue chicken pizza and it was reasonably well-topped even if the crust was a little less flaky and a lot more boring.
If you like California Pizza Kitchen outside of airports, you'll be disappointed. If you like pizza in general, you'll be disappointed. But if you're just looking for an airport bite while you're connecting at CLT, you'll be okay.
