Hello Portland. My wife and I are driving from Sonoma to Portland in August. We plan on taking the coastal route north to the Willamette Valley and ending up in Portland. I would like to hear people's opinion on spending time sampling oysters on the coast or simply waiting until we got to Portalnd and finding an oyster bar there and sampling what they have. Also, we'd like to try two or three of the better "fine dining" restaurants in the Portland if anyone would care to share their opinions on that.
The best oysters closest to Portland, IMO, are in the Hood Canal Area, on the east side of the Olympic Peninsula in Washington. The Netarts Bay oysters on the OR coast are OK for things like stews or oyster "burgers" but not best raw on the half shell, also IMO (ymmv).
On the coast is Pacific Oyster in Bay City. That's my usual oyster stop on the coast. It is a casual restaurant in an oyster processing facility and you can watch the shuckers at work.
There was a thread I posted info on here: http://chowhound.chow.com/topics/725308
You will probably find the best selection of oysters in town at EaT: an oyster bar: http://www.eatoysterbar.com/
Also, I had some great oysters at Metrovino (a fabulous fine dining restaurant I heartily recommend) yesterday: http://metrovinopdx.com/
So I say wait until you get to Portland.
I would also recommend Wildwood: http://wildwoodrestaurant.com/
