I'm a freelance writer and yogi living in Tepoztlan, Mexico where I'm running www.casadelcorazon.mx with my girlfriend. You can keep up with my other writing on www.bollocks2thewellingtons.com/
Opposite Sompet Market, up some stairs and only really noticeable if you spot one of the small signs outside, is this little hippy hangout. It has slightly inconsistent opening hours but when you find that it is open you can expect some great drinks, healthy food, and that cushions on the floor vibe - you know the one I mean.
They have a rather good bookshelf, with all sorts of spiritual titles that can help to while away a relaxed afternoon. and I'm pretty sure they have games in there as well.
It's a hub for spiritual and hippy types so you can expect to find out about all those sort of things from here, such as where the latest yoga class or rebirthing workshop is taking place.
They have yoga one morning a week here as well and on Thursday nights an impromptu jam session (which was a bit too bongos and banjos for my liking when I went but I guess that just depends on the musicians that turn up).
The Spirulina and other goodness magic shake is certainly one to boost antioxidants and give you a boost and the food was pretty good as well.
All in all, a nice vibe and friendly staff but I always get the feel that they should do a little bit more with the space they have - at the moment there is a large area just set aside for hula hooping.
