For 30€, flat rate of meat and starters. The meat is very good and tasty. The starters are average (a diversion mainly). Not worth if you are not very hungry. Strange reddish decoration.
A real Brazilian "rodízio" in Madrid, with just a little less meat verieties. Great salad buffet, good meat and friendly service.
If you want Brazilian quality steak (and find guaraná) but you happen to be in Madrid and not Brazil, then this is the perfect place. Service can be a little slow, but it's worth it!
