Neighbors MarketVancouver Food CooperativeDowntown Vancouver boosters have long called for viable grocery options. A vital, thriving downtown core requires residents, they’ve argued — and residents require groceries.Now there are two grocery stores on Main Street south of McLoughlin Boulevard; a few blocks north is Arnada Naturals, dealing mostly in supplements but also featuring some gluten-free and other foods. Safeway, the nearest supermarket, is many blocks farther up the street.The Vancouver Food Cooperative and Neighbors Market are both growing every month, pulling in the passing public while nailing down niche customers. For the ultra-conscientious Neighbors Market, 1707 Main St., that means people who want to be certain their food has been vetted as local, natural and ethical in every way proprietor Lyn Krogseng can think of.“I have become very anti-mega-corporations,” said Krogseng. “I really think they are job-destroying evil empires.”“There is a burgeoning interest in real food,” said Kirk Wright, president of the Vancouver Food Cooperative board of directors. “I think we have complementary businesses. Lyn is as local as it gets, and she’s dedicated to that. That’s not exactly our mission — we aim for a more complete shopping experience.”In fact, the Vancouver Food Co-op, at 1002 Main St., has made a deal with Burgerville to stock the local fast-food chain’s new line of grab-and-go sandwiches and snacks.
