Please BEWARE of the money changers that you will encounter at EZE in the luggage claim area. These are the first booths where you can change cash & sometimes travelers cheques and many new visitors are inclined to give them their business because of the convenience. THESE CHANGERS ARE CROOKS.... not because they will give you false notes, but because they will take you to the cleaners with the exchange rates. Please, avoid them like the plague. Its much better to use an ATM card at some of the cash dispensers or else go to the Banco Nacion or even Casa Piano once you leave the customs area.
