In Argentina they drink the green tea called "Yerba Mate" or Mate Herb - it's not really tea, but it is a good stimulant like tea or coffee - I still drink it. You can find it on the the internet now. Great stuff - Healthy too!
The siesta custom is observed strongly in Salta and many businesses, including most of the museums, shut down from about 1 to 4. This is hardly surprising given the heat in Salta and it´s one local custom that is werll worthwhile adopting.
In Salta, like in the rest of Argentina, the young people have to wear a uniform to go to school...Each school has its own uniform, so you can see many different in the street! And I loved that!!! I never saw so many girls in uniform of my life!!!! And my favourite was this one : a scottisch mini-skirt (you can imagine that boys like that too!!) and long socks!
