This particular In-N-Out is located in Marina Del Rey, about a mile from the beach and boardwalk on Washington Boulevard. The coveted west coast burger establishment serves a few basic items: cheeseburgers, French fries, milkshakes and soft drinks. There is no need for complexity with their fresh ingredients and real potatoes (not frozen). Their "secret menu" isn't much of a secret, but their are some unlisted items worth a try, like the Animal Fries with melted cheese, spread and grilled onions. It's a heart attack mess all over those golden fries you know and love. Ask for a Neapolitan Shake too, if you dare; they'll mix the chocolate, vanilla and strawberry together so there's some variety in your dessert.
