Parks On Tap, a pop-up beer garden that usually travels to a new park around Philly every two weeks, has two “permanent” summer homes this year. The first is outside Fairmount Horticulture Center Arboretum, and the newest one is at Fairmount Water Works on the Schuylkill. They serve tons of different local beers, as well as a menu of bar food like pulled pork sandwiches and soft pretzels.
