Marshall Field's Park Forest was formally dedicated in March 1955 and was the fourth branch in the chain. Originally encompassing 70,000 square feet, with a single-level sales floor and basement, the mercantile expanded into a second level sales floor in the autumn of 1956. It now covered 116,000 square feet. One of its many features was The Trail Room restaurant.
