Didn't go to the restaurant upstairs this time, stayed in the Lounge. This is easily my favorite place to relax while in DCA. They have a cocktail menu, but it's a full bar and the bartenders are happy to make you something that's not on the menu. They have a small but nice beer list, and the taps are local craft breweries. They have some nice appetizers too.
Even if you don't plan on going to the restaurant, this is a great place to visit!
