Your move, McDonald's.
Burger King took out full-page ads in The New York Times and The Chicago Tribune Wednesday, asking its rival to temporarily join forces. The United Nations set Sept. 21 as the day to celebrate world peace, and Burger King proposed opening a pop-up store in a parking lot between two restaurants in Atlanta, halfway between Burger King's headquarters in Miami and McDonald's headquarters in Chicago.
The fast-food chain also launched a Tumblr blog Wednesday that explained its proposal in detail. Burger King described the pop-up eatery as "a purpose-built restaurant in neutral territory, where McDonald's and Burger King staff can come together to prepare, package and serve our limited edition burger."
Rest assured, Burger King said it also came up with a recipe that would use "an equal number of ingredients from our signature burgers."
"Our invitation might be unexpected, but it's 100 percent sincere. Burger King genuinely wants to unite with McDonald's on Sept. 21, 2015, to prepare and serve the McWhopper and get the world talking about Peace Day," Burger King assured McDonald's. "Naturally we'll only proceed if you're on board, so we created this site to help you better understand our proposal and realize the potential."
Burger King added, "Making the McWhopper and making your involvement is easy." The company even "sketched up a few ways our proposal might come to life," but added that it's "keen to get your input."
Best of all: this won't cost customers a dime! "In keeping with the 2015 Peace Day theme, 'Who will you make peace with?', we propose guests pay for their McWhopper not with money, but by declaring their very own tray matt truces," Burger King suggested.
Will Burger King's marketing ploy work? "All these ingredients come together to build the burger some said would never happen. Some say the same thing about world peace. Together, let's prove them wrong on Peace Day, Sept. 21, 2015. Everything in our proposal is up for discussion, from the name right through to the packaging. The only thing we can't change is the date," it said. "So, let's talk soon."
It's unclear which of the chains would supply fries.
McDonald's declined The New York Times' request for comment.
