All that shines isn’t gold and this “Silver” burger from McDonald’s China isn’t earning glowing reviews. In case you’re not in the know, the latest fast-food trend is limited-edition burgers with bizarre colored buns. Here in the US, Burger King released a limited edition Halloween Whopper featuring a black bun. The bun has A1 steak sauce baked into it. We’re not sure how it tastes, but if you check out #halloweenwhopper you’ll get quite an earful, or head to Instagram/HalloweenWhopper to checkout some of the over 15,000 photos. We’re not sure if we’re up for the black Whopper, but the “silver” China burger is a definite NO!
