The Pittsburgh Zoo and PPG Aquarium will close early on July 26, but only so they can host the liveliest party of the summer. The zoo’s Summer Safari is an annual event that features creative alcoholic drinks and gourmet food provided by some of the best local restaurants. Guests can roam the zoo afterhours and are encouraged to dress in a classy, but safari-inspired fashion — so don’t shy away from the animal print dresses and safari hats with khakis.
