I went there 2 times because they were the only vegan-friendly restaurant in the zone open in the night. I think they may have improved their service quality if I compare with the experiences below).
The set menu isn't vegan but they adapted it for us each time (maybe speaking Spanish helped a lot in this). It costs $4000-4500 (depending if it for lunch or dinner) and includes a starter, a main course, a glass of ginger pisco sour, and a glass of wine or juice + bread and pebre, like everywhere. Given that we wanted a vegan adaptation they gave us more snacks.
The price may seem a bit expansive, but given that they offer the wine and the pisco, I think it's okay.
A good option if you stay in the Cerro Concepción / Cerro Alegre zone.
Cons: You have to ask for a vegan version
