Great spot, great oysters. Rowan Jacobsen on June 14, 2017 at 8:11 am Rating 5 The place that triggered the oysters-en-plein-air movement. The perfect mix of rustic and class. While away the afternoon looking out over Tomales Bay and eating Hog Island Sweetwaters as the harvesters bring fresh bags of them to shore. The house wine is a surprisingly spectacular match with Sweetwaters. Submit a Rating Cancel replySign up now to post your rating, or login here.
