Sustainability is more than a passing fancy for Bruno Feldeisen, top chef at northwest Washington’s Semiahmoo Resort, Golf and Spa, it’s his culinary calling. Besides utilizing the fruits of the sea provided by Semiahmoo’s pristine setting in the Strait of Georgia north of Puget Sound, and the artisanal bounty of local farms in-season, Feldeisen is on a sustainability mission that includes critiquing the china, packaging and chemicals the resort uses.
