Pizza place near Irvine, CA with big slices?

Smiling had the wrong shopping center name. There are actually two Irvine Market Places but neither is near UCI. The place where those two pizza shops are are in the University Town Center, which is in fact across the street from UCI. Z Pizza is at 4247 Campus Dr , Irvine, CA 92612 and Rays is at 4199, in the same center. z
