BA is a great town. Nueva de Julio, Florida, and Corrientes are the main streets in the shopping districts. The recoleta is a neat cemetary - they bury the people above gound in crypts, like in New Orleans. The Recoleta is nice though, the crypts are beautiful. I saw Eva Peron's crypt - she is actually buried in the "Duarte" crypt (Duarte was her maiden name). Steak is great, leather goods are great, and they have some really great sweaters you can buy - good wool goods.
Enjoy BA.
