This week, Steve takes the ferry from San Francisco's Ferry Building Market, for a peaceful 30-minute ride up to Larkspur, where Chef Mark Hopper has been working tirelessly on a pair of outstanding pizzas: one emerging from a wood-fired oven, the other a near perfect Sicilian square with lots of chew and crunch. Farmshop Marin is probably better known for their wood-fired pies, but you'd be a fool not to try the squares.
