Hi, all. I am visiting my son in San Fran for a couple of days. Is
Brizio's Hot Rods worth stopping by to see? Any metal working things to
see/visit?
Thanks, Bill.

First of all, to make sure you're not immediately
pegged as a tourist, refer to the city as San
Francisco, SF, or The City. Never San Fran
or Frisco.

My two suggestions are the Jeremiah O'Brien:

And the submarine Pampanito:

If you have a day to kill, check out the
