Why the best burger in Chicago is at a French restaurant might be a question for the ages. But rather than question it, just go. Go immediately and bring your appetite because a single burger at Au Cheval is actually a double and don't even get me started on the double cheeseburger! You will get your burger(s) covered in cheese, served with dijonnaise and with or without a fried egg, just as the French have always intended. That first bite will make you think you've never really had a burger until now and maybe you'll question your country allegiance. If a French restaurant makes a burger this good, what has happened to America? Well, it just got immeasurably better. That's what. So settle down, eat that burger and thank the French for their contribution to one of America's most perfect foods.
