I also discovered one of the secrets of the Shack Burger (other than lots of salt, great beef, and a potato roll) - the scraper. The griddleperson uses a commercial griddle scraper to flip the burgers instead of a standard spatula. The scraper allows them, in one movement, to scrape up the burger and all of its griddle crunch off the surface. It does such a great job that you can see the reflection of the scraper in the MiraClean during the flip.
