Chicago is in something of a pizza renaissance, and there is SO MUCH out there beyond what most of us would characterize as tourist food. There's of course classic tavern style--the original Vito & Nick's on Pulaski, or Pizza Fried Chicken Ice Cream in Bridgeport are my personal favorites. Paulie Gee's is doing Detroit style in Logan Square or New York in Wicker Park. Know Noah Sandoval, of the two-starred Oriole? He started a Sicilian-style slice shop in Humboldt Park called Pizza Friendly Pizza. Professor Pizza does a variety of styles, and Piece in Wicker Park has been doing New Haven style pies for 20 years at this point. Middle Brow by Bungalow is great, and My Pi is a personal favorite.

I would also suggest checking out Brian Erst on Instagram for Chicago-area pizza ratings; he's got an almost encylopedic knowledge.
