Diner en Blanc returns to Philadelphia in the summer of 2015 for another unforgettable evening filled with elegance, food, art and music. For the fourth consecutive year, the secret picnic in white will take over an undisclosed public space whose location is revealed only minutes prior to arrival. The date, number of registrations and new phase three lottery system will be announced next week at the official Diner en Blanc preview party on Tuesday, June 9, 2015, from 5:00pm to 7:00pm, at the Headhouse Shambles (2nd Street between Pine and Lombard streets). During the preview, vote on tables themed around Philadelphia’s top neighborhoods, sample bites from the official caterers, reconnect with old friends, and meet organizers and volunteers. No RSVP is required for this free event.
