A signature starter at Serpentine, a chic eatery housed in an industrial space in the Dogpatch neighborhood, is its savory bread pudding, a crusty hillock that tastes better than it looks (trust us). Under its browned exterior hides a frequently changing amalgam of seasonal ingredients (perhaps nettles, roasted onions, and Swiss cheese; or fennel, baby spinach, roasted garlic, and Swiss cheese), incorporated in an eggy custard full of bread chunks. For a few extra dollars, you can add roasted carrots and mixed greens to the plate, bumping up the appetizer to a perfect vegetarian supper.
