The First Timer’s Guide To Eating In Chicago - Chicago
"Italian beef sandwiches and hot dogs are almost as important as pizza in Chicago, and the Portillo’s in River North does both very well. And yes, Portillo’s now has multiple locations, but it started here - so as far as we’re concerned, it’s a must-stop. Make sure you get both a hot dog and an Italian beef, and if you know to order a chocolate cake shake, too (which now, you do), you’re basically a Chicagoan already."
