California's oldest restaurant is located in which city?

It’s on California st. & Front st. So no it’s not on the long wharf today, but not far from the water.

Brock (+ sometimes Pamo), I see you are a Danger Mouse/Penfold fan, as am I! "Good job we wore our thick socks!"

But where in San Francisco is it? I doubt Long Wharf is still there.

Question is beyond obscure!
