My first time there was excelent. High class brazilian barbecue with all kinds of meat, seafood e others. The picanha and the beef ancho were amazing. There's nothing to say about the incredible service. The maître was always asking if we needed some especific meat or sides.
Of course that its price is also high, but it is fair enough for a top class service, well located place with a panoramic view of the Lake Paranoá.
For sure I reccomend the restaurant. But be aware that you are gonna eat a lot!! So many options and everytime some waiter brings you a new fresh meat!
