Cafe 180

The inspiration behind Cafe 180 is apparent the moment you walk into Cathy Matthews's lunch-only spot: The restaurant's mission, posted above its service counter, acknowledges SAME Cafe founders Brad and Libby Birky. The couple brought the pay-what-you-can model to Denver, and Matthews adopted it for the pleasant place she opened in the summer of 2010. The specialty here is pizza -- Matthews used to own an organic dough company, and her expertise is obvious -- but Cafe 180 also serves salads, soups and other simple fare. The open kitchen affords views of the restaurant's volunteer staff chopping and mixing; some of them might even have been yesterday's customers. Doing good never tasted so good.
