So, I'm travelling to Buenos Aires next week for a conference.

Most of the week will be spent sitting in dark rooms listening to presentations (and giving one myself, yeek!), but I do have one whole day to myself to see the sights.

So I guess mostly I'm wondering whether any of the Argentinian members of the Org, or other nationalities who have visited Buenos Aires, have any travel advice they think I might find useful?

What is there to see and do in the capital of Argentina? I don't really have any specific plans so any suggestions for stuff worth doing other than sitting in my hotel room on my lonesome worrying about my presentation would be welcome.

Is there a lot of crime (bearing mind I am a very obvious tourist)? Are taxis reliable or would I be better off using public transport?
