I’d go to Phipps (very rare corpse flower blooming right now https://phipps.conservatory.org/exhibits-and-events/calendar). Otherwise, explore Shadyside restaurants, Southside and maybe the Strip if you can. Schenley park is beautiful - free movies right off Pitt campus during the summer. http://pittsburghpa.gov/citiparks/cinema-schenley Be sure to visit the Nationality Rooms in the Cathedral too - you can pay a nominal fee for the keys and explore on your own.
