The mark consists of a hot dog in a bun. The bun is yellow; the hot dog is orange and extends farther left and right than the bun. On the top of the hot dog, where it touches the bun, is a red half circle next to half of a green oval. On the bottom of the hot dog, where it touches the bun, is the end of a green pepper to the left, half of a green oval in the middle, and half of another green pepper to the right. Written in the middle of the hot dog in yellow script that connects to the ends of the top bun is the word "Chicago." Written on the bottom bun, in white capital letters, are the words "HOT DOG FEST".
