New York Mart, an Asian grocery store based in Manhattan’s Chinatown, is scheduled to open this spring in the former Magruder’s space at College Plaza on Rockville Pike. We couldn’t find out much about New York Mart — their website is written entirely in Chinese, and no one answers the phones —  but the flagship store gets mixed reviews on Yelp, and it could be tough to win over new customers in an area that already has several Asian markets. Magruder’s, a family-owned grocery chain with a long history in the D.C. area, closed its last remaining stores in 2013. There’s still one store with the Magruder’s name in Washington, but it has new owners and sells only beer and wine.
