I'm Brazilian and I love barbecue. I must say that Bossa Nova is the only real Brazilian Barbecue I saw in Bali.
The meat is awesome, If you are a meat lover like I am you really should go there, you gonna love it like I did.
Also their price is very good, specialy because it's Brazilian style "rodízio" that means all you can eat for a single price.
Congratulations Bossa Nova!
