Keep It Like a Secret
It never occurred to me what a fuddy-duddy I am. I don’t think I’ve ever ordered a secret menu item or even know about any. I just take what I’m offered. Even substitutions are a foreign concept to me.
But Mental Floss has a top 10 list of these hidden menu treasures. I’m still trying to figure out if Popeye’s “naked chicken” is skinless or just breading-free. Not that I would eat my pseudo-Cajun chicken without a solid quarter-inch of golden crust.
I can’t help but suspect that all of the customization touted in the comments wouldn’t be accommodated in NYC.
