You´re in BA for only a week and all you want to do is meet fellow American females? You didn´t need to pay and travel so much for that!!!
LOL
How about meeting some expats and some locals ALL SPEAKING IN ENGLISH, while chilling out sipping a beer, at the Club Europeo?!
The view ot the city alone from the 21st floor is worth the visit!!
Today and tomorrow, from 7pm to 9pm, (later some participants usually get a second beer down in one of the nearby pubs... optionally.)
Corrientes 327, 21st floor.
