The city is beautiful and very cheap when using the dollar. Argentines are great people as well. Clubs play mostly hard house, but make sure to visit Brasilia for an experience. Imagine the macarena to the nth power. La Sigal is busy on Tuesdays and you will always find fellow travels at Killkenny's near the city center. San Telmo also has some great pubs. Also make sure to go out to the outdoor clubs (Santo) across from the Aeroparque (domestic terminal).
My vacation also included a trip to Iguazu. The Sheraton property was pretty normal, except for its amazing location and views. As it is the only hotel inside the Argentine side of the falls. The pink hotel on the other Brazil side seemed a lot nicer although they may be more strict visa wise if you spend more than a day there. The buffet at the Sheraton was not good at all, and a horrible sample of Argentine lomo.
Thanks for the tips on Cabana Las Lilas! The place promised what every said it would. Amazing lunch with wine and cocktails for just under $20!! Be sure to visit the gelato place nearby for an after dessert treat!
