I've lived in Chicago Land for almost a year now
Haven't had Giadornos yet but Gino's East was meh
Lou Malnati's is where its at as far as the big 3 in Chicago go.
There is a Shop near our house called Rocco Vino's and they have the best Stuffed Pizza and best Thin Crust
Also at at this place called Armands and they were excellent as well
Double Dough - Thin Crust
Too many Pizza Places up here to try them all
Ad astra per aspera
