Hi! My family will be in the area next month. One day (a weekday) we were going to start early at Mount Vernon then drive up to Arlington Cemetery. I was hoping to stop for lunch in Old Town. We've never been, and would like to drive thru and see a bit and maybe stop for lunch. (Kid friendly, not too expensive). Also, what would be the best streets to drive down to get a real feel for Old Town? Thanks for your advice!
