Hiya dude, Raymond here. I am a kiwi living here for the last 7weeks.
maybe you could check out the buenos aires pub crawl which hits san telmo and palermo four nights a week, it`s a good way to orientate...and disorientate yourself around the city and meet some expat peeps. details below....
We currently meet every Thursday in Palermo beside the fountain in Plaza Campaña del Desierto AKA Plaza Armenia at the intersection of Costa Rica and Armenia 9pm
We meet every Monday, Friday and Saturday evening in San Telmo at Cyrano Resto-Bar. Located at Chile 686 (between Peru and Chacabuco), 9pm
hope this helps, have fun, it is a great city!
Raymond
