I believe Nation's most popular night is Alchemy, hosted on Thursdays. However they have other themed nights to chose from, non of which I really got into. There is a coat check when the season allows for it. $7 a head on non-show nights and 2-1 prices before 9 as well as an open bar for the first hour of opening. There are several areas inside Nation to venture through, like new rooms upstairs or catching some air outside on the great deck. There are 2 main floors one to each side. There is one more for general hanging with a small dance floor and the adjacent floor has a huge dance floor with lighting effects and occasional fog. There are 3 bars to choose from and Nation is an 18+ age venue. If you like Alchemy then you have to keep open to seasonal events as Spooky for Halloween, well known around the DC club scene.
