Shake Shack has been expanding rapidly these last few years, bringing its burgers to places as far-flung as Moscow and Abu Dhabi. But when the beloved East Coast chain opened its first West Coast location in March, it may have made its riskiest bet yet: entering the realm of In-N-Out Burger.

With its Double-Double cheeseburgers and Animal Style fries, In-N-Out has won a cult-like following. The 68-year-old chain consistently ranks as the best burger joint in America, and counts more than 300 locations across California, Arizona, Texas, Oregon, Nevada and Utah.

In-N-Out’s fans are fierce — and Shake Shack CEO Randy Garutti is among them.

“The first thing I do when I get off the plane in L.A. is go to In-N-Out,” he told Fortune last month. “I’ve always done that. I love those guys. It’s one of the greatest companies ever.”

Garutti says it’s his duty as a food lover to respect other great burger makers. Plus, California has proven there’s an appetite for variety: the line at Shake Shack’s West Hollywood location is still 100-people long for most of the day, he says.

“If you do a great job, there’s enough people to come to your restaurant; it doesn’t have to be at the expense of someone else,” he adds.
