Grace Cathedral, we strolled west on California to the Swan Oyster Depot, which has a permanent spot on the list of the Chronicle's top-100 Bay Area restaurants. One has to make a determined effort to dine there: seating is limited to an 18-stool counter (and there's always a line), the restaurant closes at 5:30 p.m., payment is cash only, and street parking is scarce. But determined efforts are what we amateur tour guides are known for.
There were five people ahead of us when we arrived at 4 p.m. Wednesday. We were seated in 20 minutes.
There are no menus at SOD. The fairly limited selection and prices are posted behind the counter.
Despite the aforementioned drawbacks the Swan Oyster Depot is definitely worth a visit. The seafood is very fresh, and the prices are reasonable.
