I saw quite a few posts here looking for different language exchanges. I just wanted to let you all know about an exchange that is organized every Thursday night from 20h-22h at The Fastnet Irish Pub in la Barceloneta (Passeig Joan de Borbo, 22).
It's of course FREE - just show up, have a drink, meet some new people, and speak! Last night we had a good crowd of about 20 people from all over the world (including locals of course). For more info add "intercambias idiomas" on facebook. The more the merrier!
