Mercedes-Benz Stadium has a Chick-fil-A but it won't be open on Sundays when the Atlanta Falcons typically play.

Seven of the Falcons’ eight regular season home games are on Sunday this season, the exception being a tilt against the Saints on Dec. 7, a Thursday night.

Chick-fil-A has been closed on Sundays since 1946 on orders from founder Truett Cathy.

Atlanta restaurateur and former ‘‘Top Chef’’ contestant Kevin Gillespie will be selling his COS (closed on Sunday) chicken sandwich from a stand on the 200 concourse.

‘‘The fast-food chain Chick-fil-A is based here in Atlanta,’’ Gillespie wrote on his website along with a COS recipe. ‘‘They’re closed on Sunday for religious reasons. I respect that. But why is it that I crave a Chick-fil-A chicken sandwich almost exclusively on Sundays? It’s like clockwork. I wake up on Sunday morning and think, ‘You know what would be really good right now? A Chick-fil-A sandwich.’ Like most food companies, they guard their secret recipe. But it’s a breaded fried chicken breast on a bun with pickles. I figured I could come up with something pretty close.’’
