Fast-food chains have secrets, and we're not talking sauce (it's just Thousand Island!). Almost every chain has a clandestine list of items just waiting to be discovered, forever rendering your typical order of a "#1 with Coke" bland. But which are real and which are just myth? To find out, I took to the streets. And ate. A lot.
How I did it
After extensive research (the Internet has been known to lie), I narrowed the list to nine chains. Any place that advertises their secret menu (here's looking at you, Subway and In-N-Out!) was disqualified. Over one weekend, I casually ordered the secret item from an unsuspecting clerk. My success rate was decidedly mixed.
