In Argentina you can order these soda bottles at some of the more old-school restaurants, and you often see old men drinking red wine with soda water (and at some places you cannot only order a soda bottle, you have to order wine or a whisky too!). You can also get them delivered to your door; the trucks that deliver the 20L bottles of spring water always have crates of soda bottles next to them. I have wanted to get onto the delivery list for soda for some time now, but need to do some more research about how to find one of the companies who still offer it. This is the Argentina that I love.
I am an Australian who has been living in Buenos Aires, Argentina for four years. My perception of the city has changed as I have adapted to my environment and new home. I am somewhere between a tourist and a local and find beauty in my everyday environment.
