Burger King is announcing more details of its plan for a special Peace Day burger -- a sandwich that might require patrons to have a bottle of antacid at the ready.

The Peace Day burger plan began when Burger King publicly reached out to McDonald's, proposing the rivals collaborate for a McWhopper to be served on Sept. 21, otherwise known as Peace Day. McDonald's wasn't ready to play, but other chains quickly jumped in.

Burger King called the result a "culinary mash-up of a lifetime" that will have parts of Denny's Bacon Slamburger, Wayback's Wayback Classic, Krystal's Cheese Krystal, Giraffas' Brutus and its own Whopper.

At this point, the Peace Day Burger will only be offered on Sept. 21 at a pop-up restaurant at 1122 Northside Drive in Atlanta. There will be 1,500 free burgers available starting at 11 a.m. and ending at 6 p.m., Burger King said.

The Miami-based Home of the Whopper has continued to promote the effort via social media, including a tweet sent Wednesday:

Burger King said each of the chains pitching in will make a monetary donation to the organization Peace One Day. Fernando Machado, senior VP-global brand management at Burger King, said the effort had already helped boost awareness of Peace Day in the United States.

"As far as McDonald's goes, any activity they undertake, whether in partnership with Burger King or on their own, would be incredible, as it will raise further awareness for Peace Day," Mr. Machado said in a statement.

At press time, McDonald's had not publicly reached out beyond its Aug. 26 letter to Burger King.
