Giordano's makes 'stuffed' pizza, a bigger, doughier version of deep dish. It's awesome. If you want a slice of heaven, order the ‘special,' a stuffed pie containing sausage, mushroom, green pepper and onions. Each pizza takes 45 minutes to bake.
Giordano's has loads of branches around town, including one at Navy Pier, but this one is particularly festive (and crowded) and has an open area where you can see pizza makers throwing dough around.
