At the FARM Café in Boone, North Carolina, diners can pay $10 for meal—or they can pay nothing. The restaurant, one of dozens of its kind, follows a pay-what-you-can model. Guests can dine regardless of their finances. It's an attempt to address food insecurity.

While some have dismissed these restaurants as limited-scale, feel-good attempts to address serious hunger issues, the cafés do foster a sense of community.
