In recent years, China has made headlines with high-profile cases of government corruption, so we wouldn't put it past McDonald's in China to come up with a pair of burgers that allegedly represent the good and evil in politics.
It really does exist, but there's some question as to the meaning behind them. Web site TheBeijinger offers an interesting explanation:
...a colleague informed us they're a play on a Chinese phrase: heibai liangdao tongchi (黑白两道通吃), 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." In other words, someone who has a foot in both camps.
A deal for the burgers is available through McDonald's China's web site and lasts for a limited time.
Fast food has been growing with astounding speed in China, in particular fried chicken chain KFC. Not to be outdone, McDonald's plans to add 700 outlets to its exist 1,300 by 2013.
Kotaku writes that the black burger features chopped onions, a black pepper sauce and the bun is topped with white sesame seeds. The white burger's bun is topped with black sesame seeds and is dressed in a sweet and spicy sauce.
The blogger behind Beijing Cream wasn't impressed at all -- he goes on a lengthy rant on the site -- but his feelings are best summed up with this excerpt: "This meal offends everyone."
