After the Chili Dog, a Chicago Dog is my hands down favorite way to eat a hot dog. It's jam packed with tomatoes, pickles, hot peppers, cucumbers, onions and green relish. I love the relish that goes on it. It's bright green, and is distinctly differant from regular relish. I can't seem to find it anywhere except at place's that serves Chicago Dogs. I usually like a hot mustard on it.
