I love the Ferry Building, which went through a major preservation several years ago. From here you can catch a ferry to Sausalito or Larkspur, but it's a destination itself for its twice-weekly produce market on Tuesdays and Saturdays or the inviting shops and restaurants inside. There's a wonderful wine shop - just pick up something to eat at another of the shops and bring it to the wine shop where you can sample the wines and enjoy your food. There's a great olive oil shop where I buy Stonehouse Blood Orange Olive Oil which I use for making shrimp scampi to add another layer of citrus. There's a Sur La Table for all your kitchen needs; there's a butcher, a bread shop, bakeries, and several restaurants. It's a charming venue.
