We’re pleased to report that the three decorative cows that greeted diners at Hilltop Steak House for so many years have moved on to greener pastures. The bovine beacons this week began grazing at MarketStreet Lynnfield, the open-air shopping district on the North Shore. The fiberglass cows found themselves suddenly homeless last fall when the venerable steakhouse in Saugus shut its doors. (Opened in 1961 by butcher Frank Giuffrida, the restaurant was owned by an entity called High Country Investor Inc. when it closed.) A spokesperson for WS Development, which manages MarketStreet Lynnfield, said the cows were corralled (and refurbished) because they’re a proven crowd-pleaser.Mark Shanahan can be reached at email@example.com.
