The Wiener's Circle is off the beaten track as far as Chicago eateries go, but all the locals know about it. It's basically just a tiny little hot dog/burger stand on Clark St with a very limited menu. That's ok, because all you need to order from there is the char cheddar burger with a side order of cheddar fries. They glop on the cheese, which is very thick, very processed, and very delicious. This is a great place to go on Friday or Saturday nights after you've been out on the town, and you're just as likely to see people in tuxedos and evening gowns (fresh from the opera) as you are to see people in jeans and t-shirts.
