Portillo's

Portillo's Restaurant Review:

Whether it's to enjoy the signature Chicago-style hot dog or creamy chocolate cake, Chicagoans love Portillo's. It’s a fast-casual phenom in multiple states. Inside the massive bi-level restaurant on Ontario Street, diners line up in separate areas depending on their cravings: juicy burgers, Italian beef, the aforementioned hot dogs and other street food on one side; salads and pasta on the other. Look for playful counter service, with orders being called up by the diner's name in a rhyme.
