Now, I don't really believe this. I don't have a favorite style, and I would put regular deep dish without the top layer of crust above stuffed myself.
Consider, this, though: Which city in America is known to have an extremely diverse, sophisticated dining scene, with very picky and astute eaters, easy access to the best raw ingredients, a food culture that is democratic and not so split between the high-end "haves" and the ethnic "have nots," as regards worthwhile dining experiences, the way that Chicago, LA and NYC arguably are, but also has no native pizza culture to speak of, and thus no "pizza baggage?" That's right, Omaha. No, wait, San Francisco.
How, then, is it possible that the diners of the Bay Area, lousy with wood burning ovens, artisnal cheeses and salume, almost uniformly (from Zagat's to the "alternative" papers to the best single board on CH) agree that the temple to Chicago tourist pizza called Zachary's is the best by far? Not just quality, but also form, style. A pound of melted cheese in a buttery crust with crushed tomatoes on top: Genius!
A Chicago pizza in San Francisco is Josephine Baker in Paris.
(Or is it Jerry Lewis?)
