Chef Robert Wiedmaier's RW Restaurant Group is taking over the rooftop restaurant space at the corner of Cordell and Norfolk Avenues in downtown Bethesda, and they have now chosen the name Urban Heights for the new venture. Wiedmaier is known for a diverse portfolio of restaurants, including the famed Marcel's in the District, and two Bethesda restaurants - Mussel Bar and Wildwood Kitchen.The rooftop was previously occupied by ROOF. While Urban Heights' menu and cuisine have not yet been announced publicly, the name does play up the hopes one originally had for the rooftop, as a nightlife destination in the rapidly-transforming Woodmont Triangle neighborhood. A fizzled "Nighttime Economy" initiative by Montgomery County instead left Roof and several other nightspots shuttered, and found popular late-night hangout Barnes and Noble closing its doors an hour earlier most nights.With the success of Mussel Bar's cross of casual atmosphere with serious cuisine, Wiedmaier might just be the man to make this rooftop the place to be and be seen.
