Behold McDonald's China black and white burgers. According to The Beijinger, the combo (you get both burgers in your order) is a nod to a Chinese saying: "Heibai liangdao tongchi (??????), which describes people who are so well-connected with both the government (that's the white side) and organized crime ('black society,' as it's called in Chinese) that they can 'eat from both sides.'" Which is different from a previous black/white burger combination, the Darth Vader/Jedi burgers from Quick in Belgium, which made diners choose between the Force or the Dark Side.
Anyway, the burgers have differences other than their colors: the black bun is beef, while the white bun is chicken. The black bun has a pepper sauce and onions, while the white bun has lettuce and a sauce with "a spicy kick with a sweet finish."
