In the Mission, now as terminally hip as it was formally poor, the St Francis is a greasy good time since 1918. Stuck beautifully in the 50's both aesthetically and menu wise it's Americana in a bun. Dig in.
Murals! where? everywhere! walls, streets, signs, windows. keep your eyes peeled. I walk a lot in San Francisco and always seem to find new murals in the least expected places. They are a constant source of inspiration, and make me wish I could paint worth a damn.
I love visiting Land's End early in the morning when the light is new and the city is waking up. There's a spectacular view of the bridge and the north bay. Makes me grateful to live in San Francisco.
