Note my comment above about disruptions involving EZE (labor issues, including slowdowns or strikes and the potential for protesters to block the highway).

Be careful about taxis and always count out the cash you're giving to the driver, watching for substitution of a smaller bill (and n change) or countyerfeit notes. It's better to carry small paper money so that you can pay close to the exact amount.

The exchange rate is great (for us, not them) but do not permit dynamic current your conversion. (I like to pay with AmEx for this reason.)

You can eat and drink very well in BsAs but I prefer the very informal (and cheap) steak houses rather than the fancier ones.
