I second that.. The local bank rates in the street are at about 3.08 to 3.12 and the last time I was at EZE (last week in Jan to pick up my wife) Global exchange was buying the US$ for about 2.82 (a whopping 26 ARP cent profit per dollar), though they claim not to charge commission or fees (because it's built into their fees).
The Banco de La Nacion is just behind the vendor booths as soon as you walk out of the security area. Simply make a right after exting the white doors and a u-turn when you finish walking through the reception area (basically walking back beside the white booths.
Any taxi company inside the booths will accept US$, just be sure to do your own calculation on their exchange rate.
