Mr. Mayor is right when it comes to Steak N Shake, hands down the best fast food chain. They have a kid’s grilled cheese special, with pickles, fries and a junior shake, that is divine. They make the grilled cheese on Texas toast-like bread. Especially if you have spent a long day driving, this is a nice light late evening meal.
I would say my favorite sandwich is tomato-mozzerella-basil with either vinagrette or else pesto for a condiment. Best to have this in the summer when tomatoes are worth eating.
