"Founded by Austrian-Hungarian immigrants who began selling franks at the 1893 World’s Fair, this factory-run stand is essentially the gold standard for a by-the-book Chicago dog: a natural-casing frankfurter with a satisfying snap, piled with mustard, onions, tomato slices, neon-green relish, a pickle spear, sport peppers, and celery salt. While the menu also lists Italian beef, Polish sausages, and Reubens, most visitors come specifically for the perfectly executed dog and often buy a package of the hard-to-find natural-casing frankfurters from the refrigerated case to take home." - ByDennis Lee
