No, not that Shake Shack. Crystal Cove Shake Shack was around decades before the NYC chain existed, which makes this tiny yellow burger hut the true original. Perched on a cliff overlooking the surf, this essential PCH pitstop always has a cramped parking lot and a line of cars inching through it, so expect a wait no matter what time you go. The menu is straightforward with burgers, fries, and a little fried seafood. The deluxe burger is a solid double cheeseburger, but the real reason to stop (besides the view) is their decadent milkshakes that are so thick you have to let them melt before using a straw. Dip your fries in them, too—it’s kind of an unwritten rule here.
