19. McGillin's Old Ale House
Address: 1310 Drury St.
Since opening in 1860, McGillin's has never closed its doors, making it the oldest continually operating bar in Philadelphia, which makes it one of the oldest in the country, too. Having the necessary room and the right attitude, McGillin's attracts drinking-game enthusiasts. A great spot for when you're feeling Irish, fratty, or some combination of the two.
