I have been here once while on holiday. An old fashioned vegetarian place, with a lunch menu (which is the time of day when you would eat your biggest meal in Bogota) presented as a buffet, where you get a soup,fresh juice, a selection of simple salads, and some rice/tofu-like dish.
When I went there, the clientelle and employees seemed to be 50+. Very nice people, but the place is a bit dark and grey, and feels like it might have been the new thing in the 70s. Lots of flyers about why you should be a vegetarian and the benefits of soy products etc., also contributed to creating a slightly out-dated atmosphere.
The food was ok, but a bit grungy and grey, reflecting the place itself. Needs an update, but is still an oasis in this meat-only country.
Cons: Grungy, Dark and grey environment
