Uno & Due
Some people might say that they like NY stlye Pizza better. But only to know for yourself is to actually go both places and eat pizza there. Going to the "chicago-style" and "New-York-Style" pizzerias in your lil bumkin town and comparing the 2 doesn't actually count.
(Chicago also has many pizzerias serving thin-crust pizzas for some of you pussies who can't handle the truth, some of which are in a style unique to the Windy City, but as a term Chicago-style pizza generally refers to deep-dish styles.
Interestingly, many prominent Chicagoland pizzerias serve only thin pizza (i.e. not Chicago-style) which is also very popular if not moreso among Chicagoans. Some area pizza parlors offer both styles, apparently to cater to out-of-town rubes who want to try Chicago-style.
