The law takes effect on Jan. 1, 2010, and follows similar legislation in New York City, California and elsewhere.
The Philadelphia ordinance applies to restaurant chains - including coffee shops, ice cream parlors and convenience stores - with 15 or more stores. It will require eating establishments to tell customers about calories, saturated fats, trans fat, carbohydrates and sodium.
Philadelphia was once labeled the fattest city in the land by Men's Fitness magazine.
