I *should be* keeping busy but you know what they say about all work and no play. I could be up for a couple hours of meeting up on a Saturday evening. I am 29 but I am *n*o*t* a big partier to be honest, but I love some good beer and chatting with folks of any age.
So I would be up for going to one of the few places in this city that has good beer. I'm sure there are some posts about yummy beer.
One suggestion I have is a place near the teatro district I found the other weekend at Sarmiento 1600 block...make sure to go up the stairs...called Cruzat Beer House. They had a large patio, which means we could talk more easily and even Chocolate Stout (surely nowhere near the best I ever had, but COME ON, in BsAs) ON TAP! I am not sure how crowded it gets on the weekends because I have never been, so that could be...er, un tema. We could always beat the porteños and go a little early, say around 8-10.
