We visited Franklin Square Park yesterday (6th & Race at the base of the Ben Franklin Bridge). One of my VP’s sisters worked on the project and we’ve wanted to go now for at least a year. Anyway, it’s the best city park for kids and adults by far. Mini golf, enclosed playgroup with a great foam base for both younger and older sets, carousel, a luncheon spot (Square Burger–a Steven Starr restaurant), and the Living Flame Memorial dedicated to the city’s fallen policemen and firefighters.
If you’re looking for a terrific hang out for a while during your visit to Center City, be sure to check it out! http://www.historicphiladelphia.org/day/franklin-square/
