I found this article interesting even though I don't speak Spanish. There are some photos. If you don't speak Spanish either and want to know more, you can have it mechanically translated via Babelfish online. Those translations are often humorous, but it translates enough of it to where it becomes generally understandable. Many of the "shop" or specialty words will not be correctly translated and you have to use your imagination there.
