Goat Hill Pizza
Potrero Hill's Goat Hill Pizza has been run by the same five founders since 1975 and markets itself, in its own words, as "San Francisco's sourdough pizza since '75" — a handmade sourdough crust that is still the house's defining claim, tying the pizza directly to the city's own Gold Rush-era sourdough bread tradition rather than an imported style. It is the clearest evidenced case this run found of the sourdough-and-local-lineage form the brief asked about, though it is one pizzeria rather than a citywide field.
