I grew up in Chicago, but I didn't grow up with Portillo's. They weren't on the south side when I was a kid. There was a family owned hot dog stand in the neighborhood that sold hot dogs, fries, beefs, sausage, etc. that was our place of choice. Absent the place I grew up with, Portillo's is an excellent replacement. Can't go wrong with the Italian Beef. Tastes like Chicago.
