For hot dogs, take a venture out closer to Ohare to Gene & Judes, classic old fashion dog and has been rated the best hot dog in the country.    I like all pizza, but each pizza place has something unique, but if you want to try a really good Deep Dish, a place called Pequods is the place to go.

For breakfast?  well, Chicago has a lot of great weekend brunch places.  My go too is The Little Goat Diner.   It's comfort food at its finest

But you really can not go wrong anywhere, I travel all over the country and Chicago is the best when it comes to great restaurants.
