The very best fish and chips I ever had was at a funky little cafe and fishing boat reservations place in Bodega Bay. It's called "The Boat House" and is on Hwy 1 at the north end of town.
I was there Saturday and asked about the fish. They used to serve today's local catch of rock cod, but alas no more. Seems there are now protective restrictions on fishing for that species. They said they get their fish "flown in daily" from Canada or Alaska.
I asked about the oysters, and they said they shuck their own out back.
I had the deep fried oysters 'n chips (french fries) and my friend had the fish 'n chips. We shared an order of servicable but bland cole slaw to go with it.
The oysters were great, and very large. A generous order was $7.95. My friend liked his fish, and the sample I took tasted good. He had about 4 generous pieces, also $7.95.
