We'll be in BA from March 13th through March 20th. This is our 2nd trip, but this time we're not super budget travelers. Any recommended restaurants that are very nice but not so expensive when considering the blue dollar rate? Made a reservation at I Latina already and that's $900 for a 7 course meal - roughly $65 with 14 peso exchange rate, which seems like a steal.

Also, I'm reading conflicting information about needing a visa for my return flight through GRU. I have to change from terminal 3 to 1, but it's all international. Will I need to get a visa? I'm a US Citizen. Wife has dual Colombian so she can just flash that passport. I read I can knock that out in a day in BA if I have to get one, is that still true?
