I'd recommend Lolita Cardelle in the Mercado de Abastos. The proprietress Dora is both lovely and knowledgeable when it comes to Galician cheeses, and she carries both classic DOP stuff (Arzúa, Tetilla, etc) as well as more modern, prize-winning local cheeses like Da Josefa, Marianne and Savel...
I would add that the closest town on the sea to Santiago is Noia, with Muros right across the ria. They are both lovely towns with a lot of history, and if you're still interested in walking, the Noia/Muros Camino is official now too, and a shorter walk than the Ingles or Sanabres...
