We got hungry and one thing led to another, namely to Pacifica. If you are ever in SF or Silicon Valley, it's worth a visit. It's a quiet little town on the coast that's falling into the ocean.
Camelot is a fake british pub, but they have Guinness, Harp, Boddington, and Bass on tap, and you can order oysters and chips.
Just a bit up the coast is Mussel Rock. The San Andreas fault runs up the middle of the peninsula (look for the string of subduction lakes) and leaves land and goes out to sea between Mussel Rock and the beach. It makes land again at Point Reyes.
