We will be renting a house on Lopez for a week in August. I'm the host, as well as the cook (it's a small family reunion and there will be 12 of us, some foodies, some picky people, some small children.) The catch is that we are flying from Massachusetts and will have only one day to shop in the Sammamish area before crossing to the island. How good are the grocery stores on the island? I'm assuming I won't be able to find things like garbanzo flour or pomegranate molasses, but what about fresh herbs, sheep cheese, etc?
