They sell lunch menus for 14,000 COP (aprox $4.30 USD), and some small things like vegan empanadas, etc...
The food is good (but not great). However, the context is what makes this place somewhat special. The place is run by two older women who look 20 years younger than what they say they are (talking about an effective marketing scheme).
All in all,if you are in the area, i think its a good choice for a vegan lunch.
Cons: a bit plain
