Comment by Tempest1981

Reminded me of the book Fast Food Nation where they describe the artificial flavor industry (Chapter 5), and visit labs in New Jersey where fast food tastes are created by "flavorists". Most of the taste comes from smell, via gas molecules released in the mouth.

The book also covers how they scout out real estate, and how they create french fries by shooting potatoes at 80 mph. (A bit different from in-n-out)

Note: don't bother watching the movie, it's nothing like the book.
