An In-N-Out is located on nearby Sepulveda Boulevard right next to the Parking Spot–a parking structure that conveniently provides free shuttle service. All you have to do is wait under the red “Hotel and Courtesy Shuttle” sign outside of any airport terminal, and when the yellow and black polka-dotted Parking Spot shuttle swings by, jump on board. It will take you literally next door to In-N-Out. Follow your nose through the back door, across the parking lot, and right inside where you need to order a double-double and fries to enjoy the best layover of your life.
There are a few things to be very careful about, however.
First off, you need to make sure that you get on the Sepulveda Parking Spot shuttle; otherwise you will end up at the Parking Spot’s Century location. Additionally, you should allow yourself at least two hours to be extra safe. The shuttles come pretty regularly and the drive is only five to ten minutes, but the line at In-N-Out can be as long as 20-30 minutes during peak hours. And then you’ve got to get back to the airport and through security once again.
