Girl's Meet up on Sunday

hello everybody, i´m a newbie to the site but i´ve been in BA now for almost 2 months. I´m American, 23, and just wondering how old are the women in the group who meet up on Sunday afternoons? I´d love to come to the one this sunday, just need to know where and when!
HiI'll be along on Sunday too, I missed last week. Sorry I can't think of anywhere to suggest to meet though, this place in Palermo is great ( but kind of small if a lot of people turn up. Galalita, you seemed to know a lot about good places to go in Buenos Aires, can you recommend somewhere?

Paintgirl, I would estimate that the girls are between 25 - 35 (but I am terrible at guessing peoples ages and its kind of rude to ask..)
