I lived in Chicago for five years and I HIGHLY recommend you go to Pequods! Giordanos is okay, but it's a tourist trap... trust me on that one. For the best pizza check out these places: Pequods on Clybourn Ave, Piece Pizza on North Ave (although this is my favorite pizza in Chicago it is thin crust style so be aware of that), or Gino's East in River North.

Good luck and get to Chicago ASAP! Best city ever!
