Sonic, with 2800 locations, is America's larger drive-in. But the thing is they are still drive-ins. Pull up to a stall, wait for a car hop, place your order, meal on a tray drive-ins. Yes the look has evolved, but the service hasn't, which is very good.
I went for a No. 2 Cheeseburger with mustard, dill pickle and lettuce. A No. 1 has mayonnaise instead of mustard. On the right, the regular Coney, with chili, cheese and diced raw onion. Nowadays the menu also offers wraps and chicken breast sandwiches. Probably good, but a little to avant drive-in for me. All manner of ice cream creations for dessert.
