Manayunk's Bisou adding a deck

Bisou, 4161 Main St. The deck will be to the right of the building.

Bisou, chef Clark Gilbert’s French bistro in Manayunk, is adding a 25-seat second-story deck.

The deck will be constructed in the space between Bisou and the building next door and accessible from Bisou’s second floor. The bistro already has sidewalk dining.

Gilbert hopes to have it completed later this summer.
