Hayes Valley is a neighborhood in constant flux — witness the condo complex that's rising where the Hayes Valley Farm's beehives and veggie rows once stood. Just across Fell Street from this construction is year-old specialty market Nosa Ria (speaking of change, the space was previously a hair salon), selling what its sandwich-board sign dubs "quintessential Spanish foods" — and we dub indubitably delicious. Its list of unique, hard-to-find imports includes grocery staples (cured meats, cheese, olive oils, etc.), wines and sherry, and treats (chocolate! Chupa Chups!). Oh yes, there is that ever-elusive jamon serrano in the house, as well as squid in ink, thick and sweety turron, and all the paella fixings you need, including tha pans. That trip to Galicia and/or Andalusia may be still in the planning stages, but you can start refining your palate ahora.
