I often question the reliability of the rating of a restaurant or hotel on Tripadvisor & the rating of #4 for the Swan Oyster Depot is a perfect example of that. I would definitely give a 5 to the staff ...very friendly, efficient & attentive. My husband would possibly give a decent rating to the raw oysters as well. That is where the 5s stop. Other than soup, there is no other cooked food. Salads are composed of iceberg lettuce with crab, shrimp or both on top, nothing else. Thousand Island is the only salad dressing offered. The long, narrow establishment is reminiscent of an old time barbershop...clutter piled high on shelves, cloth rags used to tie cabinet doors shut, in general a slovenly establishment. With so many restaurants with fresh seafood, don't be fooled into thinking this restaurant is 4th in S.F. Folly!
