The Potomac Village Shopping Center, home to Tally Ho and Hunters Bar & Grill, will welcome two new tenants by the end of this year. Village Nail Studio is weeks away from opening, and the Pure Barre fitness center is aiming for a November/December debut next to Big Wheel Bikes. Meanwhile, it looks like the center’s Walgreens store is going to survive the merger of Walgreens and Rite Aid. Some 200 drugstores will be closing in markets where the two brands overlap, but insiders tell us that both stores are doing quite well in Potomac Village. For now at least, Walgreens and Rite Aid will continue to coexist on either side of River Road.
