Adding to the rich list of Dupont Circle venue possibilities, the 6,300-square-foot One Lounge opened in December.
The bilevel venue’s first floor is a warren of four flexible rooms decorated with white or deep red walls and the occasional burst of raw brick and red Spanish tile floors. A small eight-seat bar area is adjacent to the largest space, the long and narrow 60-seat Atrium, which has a glass barrel ceiling, globe paper lanterns, and a changing collection of art work from a nearby gallery. Throughout the first floor there is assorted seating, including low black leather sofas and white canvas-covered chairs and stools.
Up a flight of stairs, the Study, which can hold 55 for receptions, has a wall of leaded glass windows, a gold-painted paneled ceiling, a white marble-topped bar, and an assortment of mismatched vintage furniture.
The small-plate menu, by executive chef Wade Hoo Fatt, brings together dishes from central, eastern, and southern Europe, such as schnitzel with crispy capers and pan-seared duck breast with lingonberry compote.
One Lounge is available for full or partial buyouts with a total capacity of 250. In late May, a flagstone terrace at the entrance will provide 35 additional seats.
