Expat connection (yeah…the name isn´t so creative) is an organization in Buenos Aires that hosts a variety of social events: winetastings, dinners, paragliding.. these are open to visitors as well as Porteños and foreign residents. For someone like me who came to BA without knowing anyone it´s been a fun and easy way to meet people. In my experience (I have 2 events under my belt) it´s been predominately Americans (who all seem to come from the Bay area..) — just sayin. Anyway, check their online calendar, a lot of the events require RSVP.
