Cars line the street, letting you know that you are close to your destination before any buildings come into view.  Gravel made from oyster shells paves the parking lot.  A wood paneled beige building with smokey blue trim and a "Live to Shuck" sign in front of it greets guests as they arrive.  You get the feeling you've stumbled into a hidden small town hangout, even though Hog Island is well known in the Bay area.  Employees go about their work in their Carhartt jackets and thigh high waders.  The place hums with steady movement.
