I'm taking a trip to Buenos Aires, Argentina, from Dec. 29-Jan5. I've been reading reviews and doing my own research online for the past several months now, but I would like to get your guys' opinions on this as well. For all of those who have been to BA, what would you recommend doing while there? Best places to go for nightlife? Shopping? Adventurous activities? Anyting else you can think of?? Please....post it!!!

Thanks in advance for sharing!
