California: In-N-Out Burger
Signature Burger: Cheeseburger.
Even superstar chef Thomas Keller is a fan of the West Coast chain—and with good reason. The cooked-to-order burgers are made with beef from Southwest ranches and served with hand-cut fries. For a messier, more indulgent experience, order your burger “Animal Style” for extra sauce and chopped grilled onions.
