Buenos Aries NYE dining and tango reccomendations?

[rblococo]

Have never been to Buenos Aries, and I understand that NYE is not the best time to go as local celebrations are typically private parties. I also read that reservations should be made well in advance as locations are limited. Will be there Dec 30 and 31 nights. We greatly enjoy excellently prepared beef (steaks), as we live in Kansas City, and getting to explore fine regional foods when we visit other cultures. We are strong tango aficionados (watching only) and would love to go to see tango performed in a club or restaurant, vs as a stage show.
