Philadelphia Zoo (3400 W. Girard Avenue) is set to take a dinosaur-sized bite out of summer with the launch of Friday Nights Dinos and Bites. Beginning every Friday, from Memorial Day Weekend to Labor Day Weekend, the Zoo will host a new evening adventure with extended hours, amazing animals, life-size animatronic dinosaurs, and prehistoric-themed foods that complement the new exhibit, Big Time: Life in an Endangerous Zone experience.
