Little Italy Mercato
The Mercato wins because it changes the neighborhood, not just one storefront. On Saturday, more than six blocks of West Date Street fill with California farms, fish, bread, flowers, prepared food, and local makers. Wednesday is the useful smaller edition: three blocks, many of the same farmers, and less shoulder-to-shoulder browsing. Direct feedback is unusually consistent about the range and energy; the recurring complaints are parking, heat, crowds, and prices at some prepared-food stalls. Go early enough that you can still see the market rather than the backs of a thousand people.
