Take a walk down Jefferson Street in Fisherman's Wharf, and you'll see a neighborhood in flux. On one side of the pavement sits the past: kitschy souvenir shops flanking the boarded-up entrance of Castagnola's, a century-old seafood staple that has been closed since March 2020. On the other side sits the future: the shiny new Taco Bell Cantina, flashy LED video boards and an entire block of newly renovated empty storefronts.
