In 2008 the exchange rate was 3 Argentine Pesos to 1 U.S. Dollar (USD). While the USD was not universally accepted, convertibility into Pesos was no problem. What I immediately noticed was how cheap certain things were like beef and public transportation. I felt like I could get a substantial meal with wine in a restaurant for a very reasonable price, and this was in a big city. Prior to their economic problems, the exchange rate was 1:1.
