I'm hoping that I'm giving a fair review, as all I can remember is all the fun I had while I was drunk...
National on 10th is a pretty fun place. As I'm sure you know, they have a bowling alley! You don't necessarily have to go bowling to enjoy the downstairs lounge! I found that the bar there is not as busy! I also found the music matched my tastes better downstairs!
This isn't the cheapest place I'd go to have a drink, but it can definitely be a blast when you are with your friends.
