Chicago Vienna Beef Hot Dogs
With their celery salt, tomatoes, onions, pickle, and peppers, Chicago hot dogs are much better than New York hot dogs in my opinion. (Pink's hot dogs in LA are still the king for me though.) The only thing I dislike about Chicago hot dogs is the relish, which doesn't sit well with a guy who doesn't really like sweet-tasting things. But put it aside, and these things are great. Here's one without relish from a quick layover at O'Hare airport, featuring Vienna Beef hot dogs, conveniently located right in front of the gate where I exited the plane.
Dan Ryans in Singapore used to serve Chicago style hot dogs, complete with a Vienna Beef neon sign in the window, but for some reason, they removed it from the menu about 2-3 years ago. What a shame.
