One of the local mom and pop shops I like to eat at when I'm under $6, often getting the Polish Dog Combo, which is a Chicago style Polish Dog with Fries. Bring Cash because they don't take debit. I like bring a packet of Cream Cheese to add to my Polish Dog, and a packet of ketchup for my fries. Inside has a lot of interesting local sports memorabilia to look at if you are in to that sort of thing.
