Burger King wrote another open letter on September 1 to announce that they will make a Peace Day Burger on September 21 with whoever wants to collaborate. Denny’s and Wayback Burgers, along with Krystal and Giraffas, expressed interest after McDonald’s declined.
“We’d like to build on your individual proposals to collaborate on Peace Day, September 21, 2015,” Burger King wrote in the letter. “Our idea would be that we all come together to create a burger that combines a key ingredient from each of our signature sandwiches.”
Peace Day was created by Peace One Day, a nonprofit that promotes global harmony and nonviolence.
Burger King also noted that they are currently constructing a pop-up restaurant and “all we need from you guys is a simple ‘yes’ plus your cooperation and a donation to Peace One Day.”
Although McDonald’s said no, Burger King has not given up hope. “McDonald’s, please take your time. We’re totally at peace with that,” Burger King’s letter reads.
