Perched on top of the Bok Building (a old converted school) in East Passyunk, Irwin's pairs Italian-American cooking with one of the best rooftop views in the city, a sweeping panorama of South Philly that earns its own conversation. The menu is simple and seasonal, the wine list is well-chosen, and the whole setup rewards lingering. On a warm night, it's hard to think of a better place to eat dinner.
