Nice.
Certainly hit Ecola Seafood Market mentioned above in CB. The crab is true boat-to-table same day. Crepes across the street!
Public Coast and Pelican (meh) are the two breweries in town. You might be just a tad early, but Public Coast owns a farm off 26 towards Cannon from Portland:

Little Yellow house is FANTASTIC if you can get a ressy.
You owe it to yourself to drive from CB to Manzanita. It has some of the most scenic sections of the 101. On the way you'll pass both Arcadia and Oswald State parks. Both home to some of the last old growth in OR:

Seriously, it's a must. And I guess now that I'm fully of topic, Ecola State Park overlook before leaving CB.

Once in Manzanita, San Dunes is the place. Then hit Tillamook Creamery on the way back to Portland!
