In-N-Out burger has a help line you can contact any time at 1-800-786-1000. This phone number gets answered by a real person who is always available to help you with directions to the nearest In-N-Out (which are sadly still limited to California and Nevada and I guess a few in Arizona).
It is somewhat surprising how many times I have used this service. Fairly frequently when I fly into California I’m on the phone to find the most convenient place for a snack. In-N-Out is a very well run operation- they have a solid system for just about everything that helps them feel efficient without sacrificing quality, and this help-line is consistent with the rest.
