Kim and Carlo’s Hot Dog Cart, on the plaza northeast of the Field Museum, serves genuine Chicago style dogs, and has a very specific policy about putting ketchup on hot dogs:

The Museum Campus (the Field Museum, Shedd Aquarium, and Adler Planetarium are all right there) attracts lots of of out-of-towners, and on a recent visit to Kim and Carlo’s I overheard a discussion among a family as they approached the cart that included the line, “I just want one with ketchup.” I did not stay to see how that went!
(One addendum to Jerry’s list of ingredients— green relish, which on a true Chicago dog is a neon shade of green not often seen outside of a Chicago dog.)
JAC: Oy, how could I forget that??? But this sign shows you how seriously Chicagoans take their dogs. Seriously, ketchup on a dog throws the whole thing out of balance!
