I first encountered the concept of pay-what-you-can cafes last summer in Boone, N.C., where I ate at F.A.R.M. (Feed All Regardless of Means) Cafe. You can volunteer to earn your meal, pay the suggested price ($10) or less, or you can overpay [towards] a future patron's meal. As Healthy World Cafe opened in York in April, I signed up for a volunteer shift and planned my visit. F.A.R.M and Healthy World are part of a growing trend of community cafes. Denise Cerreta ... runs the One World Everybody Eats Foundation, helping others replicate her pay-what-you-can model. Most of the nonprofit, volunteer-run cafes are started by individuals or groups, but Panera Bread and the Jon Bon Jovi Soul Foundation also have opened cafes with Cerreta's guidance. To date, nearly 60 have opened across the country, and another 20 are in the planning stages. Generally, 80 percent of customers pay the suggested price or more, and the remainder pay less or volunteer for meals. I think the community cafe is truly a hand up, not a handout," Cerreta said. "Everyone eats there, no one needs to know whether you volunteered, underpaid or overpaid. You can maintain your dignity and eat organic, healthy, local food." The successful cafes not only address hunger and food insecurity but also become integral parts of their neighborhoods- whether it's a place to learn skills or hear live music. Some enlist culinary school students as volunteers, some teach cooking to seniors, some offer free used books.
