Sourdough bread is probably the most affiliated with San Francisco. Ghirardelli chocolate is another. And dungeness crab is a third. Just take a cruise on Fisherman's wharf to see why. I would also say that San Francisco is known for culinary diversity (which is not exactly what you asked, I know). Being such a point of entry for so many countries East and a town focused on food means we get great food representing regions from all over the world.
Prehistoric-looking artichokes - the giant, unopened buds of a thistle family member - are on many folks' list of favorite foods. Steam the artichokes, covered, in 1 to 2 inches of simmering water until a leaf can easily be pulled from the base. In San Francisco, you can find an artichoke ricotta pizza at A16; artichoke and sunchoke gratin at Greens Restaurant; and a starter of fried baby artichokes and saffron bread sauce at Grand Cafe.
