Portillo's has recently become a Chicago staple, recently adding multiple locations including one right near the famed downtown McDonald's. This location is just as good as any of the originals. Portillo's features tasty hamburgers, fries, pasta and salads and of course, hot dogs. You can get a dog anyway you like but a true local will tell you the only way to eat one is mustard only. Don't let the crowded drive-thru here scare you off, it moves quickly and the yummy food is worth the wait.
