In most airports, I would say yes. However, @ EZE, the various prices are posted right in the middle of the baggage claim carousels. Then, before you are bombarded with the outside world, there are a series of booths, and you can ask at each one, the fare. There is competition to some degree in the authorized taxi business here.
