Neat little spot. I didn't find it quite as vegan-friendly as the last two reviewers, but it's still one of the best options in Santiago. Had some nachos with guacamole and a very tasty veggie burrito with fried tofu. Just make sure to clearly explain to the owner what you need and she will cater to you; looking at the menu, it will seem like a meatier place than it really is.
The setting is really quite lovely... don't be put off by the vague address, just start walking towards Bambu and you'll see it on the right hand side. Friendly owner and some neat products as well. Recommended!
Cons: still a mostly meat-oriented restaurant
