It's the Malbec specifically that I enjoy about the EZE lounges, not just the fact that you can pour your own booze. In LHR and FRA for example, the lounges are nicer but the wine selection is nothing to write home about. That said, with all those AA 777s leaving around the same time, it would be nice if they could have a bigger space. It helps to be traveling with someone else- one person to go fetch the wine and the other to save the seats!
