Panera Bread plans to add two more pay-what-you-want cafes later this year, part of the company's effort to help feed the hungry in a dignified way.
Panera spokeswoman Kate Antonacci said Thursday that the specific locations won't be announced until spring.
One could open by summer, the other in the fall. A third site is also being considered for later this year.
Panera opened its first pay-what-you-want cafe in the St. Louis suburb of Clayton in 2010. Two others have followed, one in Portland, Ore., and one in Dearborn, Mich.
The concept is simple: Panera lists a suggested price for food, but the customer pays what he or she wants.
Antonacci says most pay the suggested price. Fifteen to 20 percent pay more, and 15 to 20 percent pay less.
