Lock 72 Kitchen & Bar, previously known as The Tavern at River Falls, has closed its doors after a multi-decade run in Potomac Village. Chef Robert Wiedmaier, who bought the restaurant in 2015 and changed its name the following year, told MoCo360 that his lease was not renewed. Wiedmaier, whose portfolio includes D.C.’s Marcel’s and Brasserie Beck, also closed Wildwood Kitchen in 2021. No word yet on what will replace Lock 72.
