Skip Costco—for your next dinner party for 10 or 200, hit the Market Gourmet Foods. It’s the retail outlet for the Whitefish Group, a brand-management company that imports dry foods and beverages and distributes them to restaurants and grocery stores around the city. (Whitefish introduced Seattle’s Best Coffee to Canada in the early ’90s, and also designed and built Yaletown’s George Ultra Lounge.) Sparkling water, olive oils, pasta, herbal teas, even gourmet cake mixes are available in singles, case lots, or entire palettes.
