Some folks freak out when Dunkin’ Donuts comes to town. For others, it’s the McRib. Which brings us to In-N-Out Burger, a bona fide food cult, according to Business Insider. It’s coming to Colorado, in case you haven’t heard.
Journalist and author Stacy Perman wrote a book about the company and calls In-N-Out "the fast food chain that breaks all the rules." What’s behind the Bible references on the food wrappings? Why hasn’t the menu changed in more than a half century? Perman talks about that and more.
