Delicious artisan cheeses -- Cowgirl Creamery is always a stop on my scenic route trips to Petaluma. Located in Pt. Reyes Station, with a satelite store in San Francisco's Ferry Building, their full-flavored cheeses are ones I could eat by themselves. Yes, just a big hunk of cheese.
My personal favorite is St Pat, a cheese wrapped in nettle leaves (the sting is gone from freezing them before use.)
