For one day, and one day only, five burger chains will come together to produce a Peace Day Burger that will be shared… for free.
The limited 1,500 Peace Day burgers will be available Monday from 11 a.m. to 6 p.m. at a pop-up location in Atlanta, CNBC reported.
It will reportedly feature ingredients from Denny’s Bacom Slamburger, Wayback’s Wayback Classic, Krystal’s Cheese Krystal, Giraffas’ Brutus and Burger King’s Whopper.
Each chain is also expected to donate money to Peace One Day, a nonprofit group that raises awareness on Peace Day.
The announcement comes after Burger King proposed creating a”McWhopper” with McDonald’s, taking out a full-page advertisement that appeared in the New York Times and the Chicago Tribune last month.
The "McWhopper" would include elements of both the Big Mac and the Whopper, including the flame-broiled beef patty and a middle bun, according to a website Burger King set up.
McDonald's, however, declined the offer.
In a comment posted on its Facebook page, McDonald's CEO Steve Easterbrook said the proposal was inspiration for a good cause, then took a dig at the ploy by Burger King.
"Let's acknowledge that between us there is simply a friendly business competition and certainly not the unequaled circumstances of the real pain and suffering of war," Easterbrook said.
He added "P.S. A simple phone call will do next time."
Shortly after, Denny’s jumped on the “peace burger” bandwagon and took out full-page ads in USA Today and The New York Times, showing their version of a mash-up burger between Denny’s and Burger King.
The advertisement featured a massive burger with some extra toppings and a peace flag sticking out of the bun.
The other four brands followed with similar collaboration offers.
In an open letter released earlier this month by Burger King, the burger chain said its original offer to McDonald’s still stands.
“McDonald’s, please take your time,” the letter read. “We’re totally at peace with that.”
