Living it up for New Years Eve?


I'm an 18 year old university student (male) visiting family in the Buenos Aires. As much as christmas is a time for family, New Years is a time for partying till your shoes ware down and your back needs surgery. Being new to the city and since i dont really know anyone here I was hoping one of you fine folk could point me to the best party in town. I would be much obliged. Any other hints and tips would be also appreciated. A large and full bodied thank you i deliver upfront ;)
