Union coffeehouse isn’t bragging about its newly acquired La Marzocco or its skilled baristas. This community gathering spot near SMU has much loftier goals: to be a good neighbor and to inspire action in its customers as well as the business community as a whole. Led by community curator Mike Baughman, Union hosts Friday-night storytelling sessions on its Naked Stage and helps raise awareness about causes such as hunger and disaster relief. Oh, yes. And the coffee is fair trade. Union also donates 10 percent of its revenues to a designated nonprofit.
