On W. Ontario Street, Portillo's has been known to dip some of the best Italian beef sandwiches in Chicago. The restaurant is huge, with separate lines for burgers, pizza, hot dogs and more, so the lines move efficiently and the service is fast and friendly. Portillo's is a joint with plenty of character, decorated all around with Chicago memorabilia and there is plenty of space to eat. One of Portillo's gems is its Italian beef sandwich, stuffed to the brim with hot and sweet peppers and cooked to perfection, well-seasoned beef. Portillo's is the place to go to satisfy the Chicago cravings of the whole family, as their flavors are famous; the fact that the food is fresh and inexpensive is just an added bonus.
