Your friend is Paulie Gee, or the pizzaiolo at the new Paulie Gee in Chicago? Either way, get your butt in there because Paulie is the MAN. He was a regular on Serious Eats for years before he opened up his first pizzeria. He was in a totally different field but loved making pizza in his back yard. He did tons of research, got amazing at his hobby, then finally took the leap, quit the corporate world, and opened up one of the most successful pizzerias in Brooklyn, now in a few other cities as well. Such an inspiring guy - so much so that he actually inspired a former Serious Eats editor (Adam Kubam) to open his own pizzeria as well. He makes some incredible bar-style pizza at Margot in NYC.
That image of the square cut deep dish is so very NSWH. Heck, I'm fully sated at the moment and I want that in my mouth right now. I may have to plan a trip to Chicago.
