Love this place. My wife grew up here, and once a year we make a pilgrimage back to this town surrounded by an ocean of corn.
And at LEAST once a year I make sure lunch means a sandwich at the Brown Bag.
The food is always great. Lines do form at noon, so here's an idea...don't eat at noon. We either beat the lunch rush or hit the place after the rush is over.
I've NEVER had sandwich here that wasn't short of fantastic, and it is 'lunch in middle-America on a courthouse square' at its best. I don't eat deserts, but the line-up looks absolutely solid.
