Just two quick notes: Apparently some Argentine bank cards will still be accepted (lounge website says "contact your bank for information"), and youngsters under-16 who are sons/daughters of cardholder are allowed inside provided they are flying with the said cardholder.
IMHO, the Lan lounge is currently the best at EZE. But I still haven't tried the Star Alliance and AA/IB ones.
