Craft beers are all the rage in Argentina, and have been for at least 3 years. Perhaps they are a cheap enterprise.
However, most of them are not worth mentioning, although are widespread in bars and stores.
Palermo, were beer places are as ubiquitous as homeless people on the streets, has TONS of beer places. However, my worth-going-list boils down to one, which is currently making just 5 beers. Sometimes it makes 8. I don't understand why the selection fluctuates, but I am no expert.
I am also a sucker for draught beer, so I am even more limited when going out. Unless I am at a craft beer place, nobody has craft beer on tap.
