Ferry Building San Francisco, CA
It was a toss-up on the prime "San Francisco" food item to add here. Sourdough bread would seem to be the winner, but you will get that everywhere in the city, even with another spotting item below. So the choice here is garlic fries. A perfect combo of fresh local garlic, usually from the garlic capital of Gilroy, CA, with the classic dish of french fries.
