Relax. In-N-Out isn't going to change with the death of cofounder Esther Snyder. From the Los Angeles Times:
The new head of In-N-Out Burgers said Monday that the venerable restaurant chain would remain in family hands and stay true to its time-tested strategy -- a simple menu and slow but steady growth -- after the death of company matriarch Esther L. Snyder....
"The general perception in the industry is that it's under-developed -- that there could be a lot more of them," said Randall Hiatt, president of Costa Mesa-based consulting firm Fessel International.
The trick, Hiatt said, is to achieve that growth without losing the In-N-Out mystique.
"Because of the way they have restricted growth, it still has that cult kind of buzz," he said. "Like Krispy Kreme had but lost when you started to see them at every gas station."
