"Open since 1907, the Walnut Room survived Marshall Field’s transformation into Macy’s with most of its menu intact, including the chicken pot pie. (The recipe, developed by a millinery clerk named Mrs. Hering, actually dates back to 1890, when it was served in an earlier Field’s location.) Lunch there is a classic Chicago experience, especially during the holiday season, when the room is dominated by an enormous Christmas tree." - Ashok Selvam, Naomi Waxman, Eater Staff
