Portillo's is a chain of restaurants that specialize in serving Chicago-style food. Portillo's is located primarily throughout the Chicago metropolitan area, and also has two locations in southern California. Owner and founder Dick Portillo opened his first restaurant from a trailer with no running water in 1963 in Villa Park, Illinois.
Several of the later locations were built on property that was formerly the home of closed down Dog n Suds drive-thrus. Today, each location has different themed decor that reflects Mr. Portillo's love of history and of Chicago.
