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, so don't arrive starving.
Giordano's has loads of branches around town, including one at Navy Pier, but this huge, open, industrial-vibed one is particularly festive.
