These giant hunks of stone pop out all along the grassy Schuylkill River banks. The constant hum of the Schuylkill Expressway and the polluted river don't make for the most scenic of alfresco spots, but with a plate of croissants, cream puffs and focaccia with walnut brie from Miel Patisserie, the French Riviera is never too far away.

There must have been a park publicist lurking in the bushes while we were picnicking here—an all-star Norman Rockwell cast had assembled for our visit. Grandpas played, couples walked their dogs, and a menagerie of animal sculptures decorated the tree-lined landscape. Grab a spot at the foot of the graceful Victorian-era fountain and enjoy Sunwishes' tofu chili cheese dogs.

This volunteer-maintained Gayborhood park has a soothing fountain and is shrouded by trees; in fact, it's the only open public space between Washington Square and Broad Street in Center City. And just down the block sits Effie's, a no-frills Greek establishment with pitas and baklava.

Buy a bunch of junk food at the Old City Food Market and be a boardwalk bum. Behind the Seaport is an elaborate nonoperational fountain perfect for picnicking. Sit on its steps and admire the lovely horizon of, um, Camden.

Looking to eat on Rover's level? This is the dog park to do it. There's an enclosed area where your furry friend can run freely, a lush garden and plenty of benches. Pick up a 15-ounce brisket sandwich from the Famous 4th Street Deli and just try to save room for the potato-and-frankfurter-stuffed knishes. Not to be missed: the fireflies at dusk.
