What is a meal at Panera Bread worth to you? A former Panera location in a prosperous St. Louis suburb has reopened as “St. Louis Bread Company Cares,” a restaurant where customers can select a meal, then pay what they think the meal is worth–or as much as they can afford. If customers can’t afford to pay anything, they can volunteer to work there. A not-for-profit foundation runs the restaurant, which opened this week.
