For people who seek something special - go for it.
Lovely atmosphere, very nice drinks with a good set of special Pisco Sour (the national aperitivo) and great food, the appetizer on the house is already an experience, we then moved on to Goat tongue and horse steak. But there's also a decent set of vegetarian options.
Make sure to book ahead, it's quick and easy over their own homepage.
Would clearly recommend to at least experience once -
