After a year in San Clemente we have yet to find a local pizza we really like. We're about half-way through a 'try-every place-in-town' search and have reached Z Pizza (which has several franchised locations in OC). First try was pretty promising, except the basic sauce is too understated for our taste.
Their menu shows a variety of sauce alternatives, along with one of the most extensive lists of toppings, spices, etc, we've ever seen. So.......... we need some input from experienced Z Pizza'ers..
As a frame of reference, we love the pizza at Antonucci's in Mission Viejo, and also at Peppino's (except for the local San Clemente location - not same owner...... for some reason the sauce turned bland a couple months ago). Even 'extra sauce' didn't do it for us.
