There is no "inside". You order at the window and they call you or bring the food out to your car. The food is great, hot (or cold if you get icecream) and service is quick. The menu includes the usual fast food stuff like burgers and fries, but on a hot day nothing beats a cold blizzard or an ice cream cone.
If you don't want to take your food home there are some benches and a little tree filled area to sit at.
