On the hunt for that perfect cocktail

I'm looking for the well-executed cocktail. I seek to journey through DC to try everything traditional and avant-garde. I'm an equal opportunity guy who doesn't discriminate between your ultra swanky speakeasy with a resident mixologist or your random neighborhood bar. I've lived in this city for nearly 8 years and I've experienced the good, the bad and the ugly. I seek not only places that put a great deal of thought into offering a wide menu of elixirs but also that bar that serves that one drink that is out of this world. If you've got recommendations for me, please send them in. Let the drinking begin.
