Drive in. Lights on for service. Service to your car window, eat in car. Burgers are different than your typical grease fired burgers. I believe they are steam grilled with onion water - not sure exactly, but they are good! They are thin patties, so get at least a double, and maybe a triple. The onion rings are a must. Order them in Swenson's lingo (Onion rings, well-done, broken) = crunchy, golden brown, onion ring bites! Inexpensive. Busy in summer months, but they do have a big lot and can handle many customers at once.
