I've lived in Chicago most of my life and if I could only have one pizza, it would be Giordano's. I usually order the thin crust with sausage and mushroom though of course you need to make time for the stuffed pizza as well. It's delicious and will feed you for days. Yes, there are a number of memorable pizzerias in Chicago but for me, Giordano's is the best of the bunch. Enjoy!
