In "sleek" Asian-inflected digs off U Street, this "cozy lounge" with low leather sofas and dim lighting has a "classy" vibe and "grown-up, sexy" patrons; with "really good" DJs spinning, it's a "cool" spot for dancing, even if the "small" space means it gets "a bit crowded"; P.S. it's the "perfect setting" for private parties.
