We stopped for lunch at the Chuck-A-Burger Drive-In Restaurant, not quite knowing what to expect. It looked intriguing from the outside, in a retro type of way. There were parking spaces out front reserved for drive-in service, so we made sure to park farther from the building for the "Inside Service".
Walking to the door, it was a little confusing. The part of the building that juts out and has its own door is where the drive-in customers are serviced. To eat inside, you must go through the door under the "Inside Service" sign.
