In-N-Out historian shows off lesser-known secret menu items like the Flying Dutchman (video)

In-N-Out's secret menu are the not-so-secret items that you can order if you know the code names. Of course, there's "Animal Style," "Protein Style," "4×4," etc. But there's more. So much more.

Chef and Los Angeles restaurant historian George Geary visited In-N-Out with a KTLA news crew to taste an array of the lesser-known secrets, including Sport Peppers (pepperoncinis smashed into the patty), the Flying Dutchman (two piece of cheese, two patties, no bread), and Lemon Fries (lemon squeezed onto the potatoes).
