I am not a fan of chain restaurants, but I love love love CPK! I first had their pizza in Hollywood and that started my obsession!
This is the only location I know of in Pittsburgh, so we have visited a decent amount of times. I'm semi-ashamed to say (no I'm not) that I've only ever ordered the BLT pizza! I cannot stray from it! Sadly, they took it off of the menu, but they are still able to make it, thank goodness! I could truly eat it every week it's so good. Everything tastes fresh, not like it was frozen and full of preservatives. Whether it is or isn't, it at least doesn't taste like it!
As far as the restaurant itself, it has always been clean and the staff has been friendly. The most recent time we were there we had one of the most friendly servers I've ever experienced. He was extremely nice, helpful, and attentive. Thank you for making our dinner enjoyable!
