The photo speaks for itself: There were lots of people out buying the Chicago favorite; the hot dog. (Yes those are giant hot dogs on top of the building.)
Some of the purchased dogs were Superdawgs, "comfortably lounging in Superfries." And all of them had NO KETCHUP.
Hot dogs - or red hots - are not served with ketchup in Chicago. Instead the traditional dog is served on a warm poppy seed bun, with sweet pickle relish, chopped tomatoes, pickeled green tomoato, chopped onions, a dill pickle spear, "sport peppers" (they're hot!) and mustard.
We were lucky enough to visit the friendly car hops at Superdawg. The dogs and the hand-cut fries (that still included some 'tato skin) were delicious. All those flavors of sweet, sour, spicey and meaty umami were delicious. And of course, the sunshine made them taste even better.
