Londoner new to Bs As

#1
Hey guys
I'm a 27 year old Englishman arriving in Bs As this Saturday looking for fellow expats (U.K, U.S., wherever really) to hang out with that evening. I'll be in Buenos Aires for at least a month though (am there to do a TEFL course) so obviously cool and welcoming people will find a good, highly outgoing friend in me beyond Saturday evening.
Is anyone around who is happy to string along a hapless but thoroughly sociable newcomer that evening? Cheers.
Omar
