The most horrifying and bizarre fast-food menu items of the last decade

The Double Down was one of the most memorable fast-food menu items of the decade, seared into people's memory following its 2010 launch.

The New York Times even had food critic Sam Sifton review the menu item, stalked by the "geek paparazzi" at Eater while he ate. His verdict: "a slimy and unnaturally moist thing, with flavor ginned up in a lab."

The hot dog stuffed crust pizza hit Pizza Hut menus in 2015. According to Business Insider's taste test at the time, the pizza was okay, but the crust was too salty.

"The pizza portion itself was fairly standard Pizza Hut pizza with a soggy crust," a tester said."The hot dog was salty, the pretzel surrounding it was salty — there's just no way I could eat more than a slice of this."

Also in 2015 — a wild year in fast food — Buffalo Wild Wings rolled out a new sauce made with Mountain Dew, lemongrass, ginger, red peppers, and soy sauce.

Business Insider's Hollis Johnson somehow liked the Whopperito when it hit Burger King's menu in 2016.

"I'll admit, I came into this expecting a sopping, cheese-laden torpedo; I stand corrected," Johnson wrote. "The Whopperrito, despite how unappealing it may sound, is a delicious and flavorful item that exceeds expectations."

The Mac 'N Cheetos divided Business Insider when Burger King added them to the menu in 2016.

One critic said: "As a purveyor of absurdly flavored garbage guilt food, such as gas station corn dogs and dill pickle sunflower seeds, this was seriously disappointing. They really need to lean in more on the Cheeto flavor. It was like they took normal breading and made it orange, it didn't have that super-duper fake Cheeto cheese flavor that I wanted."
