Top Dog

New yorkers may demur, but nothing beats a genuine Chicago hot dog. For the uninitiated, that's a pure beef frankfurter, made with natural casing and covered with a lurid kaleidoscope of toppings: yellow mustard, emerald green relish, white onion, juicy red tomato, forest green pickles, and tiny, olive-colored chilies, known locally as "sport peppers."
