First of all, I'd throw out of consideration all the delivery houses: Papa John's, Domino's, Pizza Hut, and Little Caesar's.
My vote goes to Round Table. Good for regular crust, anyway. I'm a big fan of the Italian Garlic Supreme, which is great because they use NO TOMATO SAUCE!
Not a fan of California Pizza Kitchen, and BJ's has gone way down. Claim Jumper does make a pretty good pie.
