Parky’s Hot Dogs has been turning out thousands of Chicago’s beloved handhelds since the 40s, likely because it has a sausage up its sleeve that’s made specially for them by a local butcher. The Forest Park-based fast food hot dog stand is great for all things Italian sausages and sandwiches, but the Chicago dog is the true standout. The Windy City is chock full of options for the dog, and the vast majority of them are anchored by Vienna all-beef sausages. Parky’s is not: it’s a mixture of pork and beef and it’s the stand’s custom, made to order sausage that you can’t find anywhere but here. For a unique twist on the Chicago dog, head to the corner of Harlem and Madison, and while the sausage itself is different, the same rule still applies: never put ketchup on a Chicago hot dog.
