NEW YORK – Maybe it’s Halloween bringing out the creepy, weird and interesting fast-food finds. Whatever the reason, QSRs in the U.S. and abroad are surely generating a pretty solid social media game with their unique entries to menus. Some have a potential gross-out factor, while others are finding fans.

First up, the cheeseburger stuffed with peanut butter cups. The combination of chocolate, beef, cheese and peanut butter is the creation of a Canadian chain called Works Gourmet Burger Bistro. The chain is also known for its Crappy Tire (pineapple and brie) and the Elk on a Beech (elk meat, avocado, Beechhouse sauce, sundried tomato and feta).

Foodie website Delish.com says that the burger “leaves a strange taste in our mouths," and Food and Wine calls the creation "the scariest Halloween trick of all."

Then there’s the burger byMcDonald's in China and its limited-edition Modern China burger, complete with grey-colored buns. CNBC writes that China, a region where brightly colored fast food burger buns are commonplace, is also home to KFC China’s pink bun, and Burger King Japan’s black, orange, green and yellow burgers. 

Some say McD's grey-colored burgers in China appear to be silver, industrial or granite-like, and TIME magazine describes it as "the new grey burger that horrifies the Internet."

But there’s nothing spooky about Buffalo Chicken Fries at Burger King, the limited-time French fry-shaped chicken tenders that will now be sold with a dusting of buffalo-style spices rather than sauce, to keep the mess to a minimum and maximize "dipping and handling," reports CNBC.

"We knew there had to be a better way to Buffalo so we took the same flavors found in traditional messy wings and innovated on it the BK way to create Buffalo Chicken Fries," Eric Hirschhorn, chief marketing officer Burger King, told the news source.
