Not everyone here in Chicago likes a salad on top of their dogs.
I prefer yellow mustard and raw onion on a natural casing dog served in a plain bun. Occasionally a little celery salt winds up on in, which is fine too.
When I travel, I almost always try and stop at a local hot dog stand to get one done up the way the locals like them.
yes, exactly. I grew up in Chicago and have been eating chicgao style dogs since I was a toddler. While a fully loaded CSD is something to try, most chicagoans I have ever met or observed craft their toppings from what is available and what they like. I choose (the yellow) mustard that is common, onions, celery salt, and a pickle. My Dad who just passed away at 90 and ate hot dogs for all of those years, loved his with mustard and green relish which he called picalilli.
When I was about ten i was taken to a baseball game in Milwaukee where I first discovered what good german style brown mustard does for a dog. Loved it but normally choose the yellow mustard so common in Chicago on my dogs, although other than corned beef sandwitches prefer the brown or other mustard varieties on most dishes.
By the way, I do not think that one can make teh case that a hot dog is more common or personifies the american roadfood experience any more than a burger, or any less! Just two top favorites.
