Chicago is a city of pizza. However, for the most part, the rest of the country thinks we all eat pizza of the deep-dish variety. Although I also take pride in this (especially from Giordano's or Lou Malnotti's), for my money and for my heritage's sake, you can do no better for thin-crust pizza, than by choosing Beggars Pizza. This is a local chain, which started in Blue Island, IL (south-suburban Chicago very near where I grew up), and has sprouted to about a dozen restaurants in the area, staying exclusivley in the southern suburbs. There is something ridiculously different and beautiful about a Beggars thin-crust; the dough itself isn't all that remarkable - although it is NOT greasy - but the semi-sweet sauce and loads of finely shredded mozzerella cheese (never mind any other ingredients you'd care to add) makes this very different than other pizza joints (which can run from greasy crusts to bland sauce to poor cheese). Ask just about any Chicago-area resident who lives south of the Stevenson Expressway and west of Indiana about what is their favorite pizza, and invariably Beggars will be mentioned. The "lay it on thick" but it's still not considered deep-dish, or stuffed, pizza. It's a treasure of the Chicago area!
