Feria de los Mataderos, Buenos Aires

This is a fair on the outskirts of town, where gauchos and locals gather every Sunday to enjoy cultural events, the market, the local food, etc. It has a great atmosphere.

I know that the llama makes this place seem really touristy, but it's not. The llama was the only picture I took. Click here and here for the videos, which give a much better idea of the atmosphere than any photo could.
