Drinkers, foodies and do-gooders unite seasonally for a walk-around tasting event at the historic Ferry Building in support of the Center for Urban Education about Sustainable Agriculture (CUESA). The theme for this summer’s fete is Picnic on the Plaza, a unique chance to enjoy a citified al fresco outing with tasty creations from some of the city’s best regarded chefs and bartenders from hotspots like 15 Romolo, Lazy Bear and Tradition.
