Hungry in Glens Falls, we pulled to the curb to investigate a storefront diner on South Street. "You looking for the hot dog place?" a pedestrian asked. "It moved." He pointed up the street. Interesting as the diner was, we figured that the unsolicited tip was worth following. So we drove a few hundred yards to New Way Lunch, which has a sign outside boasting that it has been world famous since 1919.
