PHILADELPHIA – The end of an era is here, and Devil’s Den, Philadelphia’s leading craft beer bar, is saying farewell to loyal patrons, fans, and neighbors with one celebratory streetside Blow Out Block Party on Sunday, October 2, from 1 pm – 7 pm, with the street at 11th & Ellsworth, blocked to allow for a bevy of fun-filled activities, great beer, food, music, and some of the beer maven and Devil’s Den owner Erin Wallace’s favorite causes.
