Vienna Beef Franks are the heart and soul of a Chicago Hot Dog. I stopped looking for them locally a long time ago. Today, at Walmart, on a lark, I thought I'd ask. I was amazed to find that they stock them. Hot damn, I'm having a couple of Chicago dogs for lunch!
UPDATE: Wally World also has Butternut "Chicago Style" hot dog buns. (They're just regular buns with a poppy seed topping.)
I've eaten nothing but Chicago dogs since discovering Vienna Beef Franks at Walmart over a week ago.
