Why is it called In-N-Out?
The very first In-N-Out Burger opened in 1948. The creation of Harry and Esther Snyder, it was based on the car-hop system that was popular in California at the time.
Customers would pull up in the car park, an employee would come to their window and take their order and serve their food. In-N-Out!
It went on to become one of the most popular burger fast food joints in the country. It’s still family owned and family operated! Now, there are now over 300 In-N-Out restaurants in the US, most of them on the West Coast.

What’s the difference between In-N-Out sauce and Thousand Island dressing?
Thousand Island dressing normally has a bit of a kick to it. It can contain anything from tabasco and paprika to Worcestershire sauce and lemon juice.
