Saturday's event at Waterbar (399 The Embarcadero S. at Folsom) is still on. Expect a shucking contest, a slurping competition, and an oyster sauce-making battle. Tickets: $50, which gets you five food and wine tickets (additional tickets will cost you $5 each). Tastes include heirloom tomato gazpacho with oysters from Farallon, chili-lime cured oysters from Fish in Sausalito, oyster BLTs from Epic Roast House, Waterbar's chowder, and ginger-chocolate chip ice cream sandwiches from house pastry chef Emily Luchetti. OysterFets is a benefit for the San Mateo SurfRider Foundation.
