The place just to eat, not to chat. 100% vegetarian.
I was very satisfied with variety of raw ingredients in the buffet. A plate for buffet costs 5 euros and with a drink (raw tomato juice with some ingredients) it was 7 euros (and you can take a bottle of water). I was very-very happy.
But there are very few information in Spanish and no information in English at all and the stuff doesn't speak English at all. A visitor who spoke English helped me a lot.
As I understood the cafe is opened from 13:00 till 16:15. It strange but when I was going out at 16:30 it was already closed.
Cons: stuff doesn't speak English at all, not enough information about the menu
