Hog Island Oyster Co. is based out of Tomales Bay, just north of San Francisco, with oyster bar locations in both San Francisco’s Ferry Building and Napa’s Oxbow Market. As its name implies, the restaurant serves up fresh oysters and other shellfish of all varieties, prepared very simply.
I’ve been to both the SF and Napa locations a couple of times. They’ve been very popular with both locals and tourists; lengthy waits are commonplace at this no-reservations spot especially on weekends. While spending the long holiday weekend in Napa, I stopped in for a lunch meal.
