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.
And it passes by more interesting landmarks too. You'll see the Main Ferry Terminal, Tadich Grill (opened in 1849), Montgomery Street (Wall Street West), Chinatown, the Fairmont, the Mark Hopkins, the Pacific Union Club, Grace Cathedral, and the infamously seedy Polk Gulch.
