In its 61 years, little has changed about California's In-N-Out Burger. The family-owned fast-food chain has never franchised or gone public, and the simple menu is basically the same- though insiders know that variations are available on the chain's "secret menu". Besides its devoted following, In-N-Out is notable for its business philosophy. Part-time associates are paid a few dollars higher than the industry average, and store managers earn $100,000 a year with benefits. It's been a successful strategy for the company, as In-N-Out beats McDonald's and Burger King in per-store sales. Larry Mantle talks with Stacy Perman, author of "In-N-Out Burger", about the success and cultural impact of the California institution.
