At a preview party on Tuesday at the Bourse Food Hall, officials announced the eighth annual Diner en Blanc will take place on Aug. 22.
"The date is the big reveal," said co-host Natanya Dibona, "and this one's important to reveal because it's not the third Thursday (anymore). It's the fourth Thursday this year."
Then, party-goers meet up with a group leader and head to the secret location together.
This year, she anticipates 6,000 attendees.
The preview party included a table decorating contest, and the winner's design illustrated the city's former Bastille Day celebrations at Eastern State Penitentiary. The theme of the contest was "showing off festivals and celebrations."
While Dibona, of course, wouldn't share the location of this year's event, she did say the winning table is a clue. She offered another hint:
Previous Diner en Blanc pop-up picnic locations have included the Logan Square fountain, the bridge in front of 30th Street Station, South Broad Street, the Navy Yard, the steps of the Philadelphia Museum of Art, Franklin Square, and Dilworth Park.
