If you want to get some serious shopping done go to Calle Florida while you are in Buenos Aires. There are stores ranging from Lacoste to Nike up and down this great place. There is also the Galerias Pacificas mall which was more great stores. Since my hotel was close to Calle Florida I also ate there a few times and really enjoyed the ambiance. The only thing that I did not enjoy about this street is that there are salespeople every 20 feet (no kidding) asking you to come into there stores. At first I was nice and went into a few stores but then realized that I was better off just entering the stores that I thought were worth my while. You are better off telling the salespeople "no gracias" (no thanks) and just keep on walking.
