Places worth eating on Hwy 5 from SF Bay Area north to Canada?

Hi all,

My partner and I are planning a road trip for July. The destinations are Lummi Island (where we will feast on spot prawns one night and the next night the chef's 5-course tasting menu at the Willows) and Vancouver (where we already know where we want to eat). We want to plan our route so that we are near somewhere good to eat each evening around dinnertime. I already know good places on the Oregon coast and Arcata, but this time we are taking Highway 5 to save time. Suggestions? it doesn't have to be fancy, and in fact it's probably better if it's not (given the chances of fancy food being overpriced crap once one leaves civilization), but we would like food that is well prepared from scratch--any genre.

Thanks in advance,

Alix
