Concierge.com's insider take:

Named for a star used by sailors to navigate, Atria is the Vineyard's first certified organic restaurant. Christian Thornton, the chef (and co-owner, along with his wife, Greer), sources ingredients from island farmers and fishermen. He changes the menu daily to reflect what's freshest—lightly seasoning and wok-firing a two-pound lobster caught just off-shore one day, and wrapping cod in prosciutto with a drizzle of lobster and lemon butter the next—but the dish the locals praise the most isn't on the menu at all: the island's best cheeseburger. (The big, juicy burger is available only in the Brick Cellar Bar—a local hangout with leather club chairs, saltwater fish tanks, and live music). The large, reasonably priced wine list emphasizes Napa Valley (Thornton's original home), and in addition to the main dining room—with white tablecloths and rustic wooden chairs—there's outdoor dining on a back deck.
