Construction is humming along at the new O’Donnell’s Market, where owner Bill Edelblut hopes to open before Thanksgiving at Potomac Woods Plaza off Montrose and Seven Locks Road. The market will offer fresh meats, fish and seafood plus a salad bar, grab-and-go items, and a bakery stocked with bread, pies and the famous O’Donnell’s rum buns. Edelblut, whose family ran the O’Donnell’s Sea Grill restaurant chain for almost 100 years, says he thought about taking it easy after selling his last restaurant in The Kentlands two years ago. “But it turned out that 18 months of retirement was enough,” he says. “I’ve always wanted to do a market where people can buy something to take home rather than going out to dinner. We’ll have some products that are pre-cooked, and some that are raw and come with heating instructions. And people will be able to just call up and say, ‘Hey, Bill — cook me a lobster and two crab cakes, and I’ll be there in 20 minutes to pick it up.'”
