Unexpectedly memorable - An Eventective User from Washington, DC

I attended a wedding reception here, and it is THE most memorable location for a reception that I can remember. And I've been to PLENTY of weddings. As an event planner, I see many benefits of holding a social event here - not the least of which would be that there would hardly be a moment without conversation thanks to the ambiance and environment. Tremendously well-kempt, the Mansion is an eclectic, unexpected gem of location.
