We learned from the Washington Business Journal that Zengo, Richard Sandoval’s restaurant in the Gallery Place complex (781 7th St NW), will be replaced by Circa, a local bistro chain. Circa already has the Chinatown location posted on their website.
Notably, Zengo opened in 2005 at the height of the Penn Quarter area building boom before the real estate crash in 2006. It seems that many restaurants have about a 10 year lifespan before the concept wears out and they need to be rehabilitated or replaced. This is another anecdotal example of that lifespan.
