On Main Street in chic St. Helena, pull over at Cook where a Carrara marble wine bar awaits with local temptations. This spot reflects its wine country setting with taste and whimsy: antique tin-framed mirrors and black-and-white vegetable prints adorn the walls; dark wood covers the floor; and a playful bovine lantern is mounted like a trophy on the wall. While solo diners may prefer a spot at the bar, white linen topped with butcher paper make the close-knit tables a cozy place to dine. With pride, the kitchen brings to you reasonably priced Cal-Italian fare, with daily specials on the blackboard. Sample steamed mussels in spicy tomato broth; red trout stuffed with roasted fennel and fingerlings; and a flourless chocolate cake dusted with grey sea salt.
