Late night study spots ??

I was looking for suggestions of late night spots to study around town? I know the Mill is open till 10. Any other spots? Any spots you can think of where I could chill and work on a computer and have a beer? One of my favorite places ever where I used to live was a coffee shop by day/bar by night that had a bunch of tables to work on— it would be awesome if there was something like that here!
