Clubbing in BA

It's nice to not have to leave at 2:00AM. Actually things get started at 2:00am. The Subte trains stop running at 22:00 but a there are a gazillion taxis about so no problems getting home. The most obvious thing to do is start at midnight and leave at 7:00AM. I read this somewhere to bring your shades not for the night but for the next morning when you leave after the club closes. Must not forget next time.
