The Hot Dog as 'Perfect Recession Food'
WBEZ Chicago: "Turns out the Chicago dog has a good 'pedigree' for surviving tough times. The Chicago style hotdog, loaded with veggies and condiments, got started back during the late 1920s. You could get your meal on a bun for a nickel; at least one hotdog stand called it a 'depression sandwich.' And while it may be overselling it a little to say sales now are 'steaming' or 'red hot' these days at Weiner and Still Champion, they're good."
