I suspected you'd like that one. I have spent about 5 weeks in BA, all together, for work. I got taken to Bomba de Tiempo by a local friend, which was a blast. It's worth knowing that BA is not just tango. It's a great city. Really beautiful. I made some really nice friends there, too.Have you been to Buenos Aires Moxie? I think the poster @Alien was from there. Hopefully he'll drop by and share his insights into the city and also the Argentina Open thread.
Like the second video especially.
