There are at least two Denver restaurants with a Chicago-themed name - a sub shop and a pizza joint. The sub shop doesn't promise a good beef sandwich, so we let them be, but the pizza place comes very close to offering a Chicago-style pie, which we just had to investigate.
Mark went in and talked to the regional manager, who seemed very nice and, if given the benefit of the doubt, probably has never had even one slice of a true deep-dish sausage or a crispy bit of heaven that is the thin crust with toppings slathered to the edge. So if he's told this is Chicago pizza, he's acting in good faith. But hey, pal, sometimes you gotta question your faith.
