Although it's situated on the large sidewalk of Avenida Atlantico (parallel to Copacabana Beach) it's in a comfortable quiet spot, (close to the seafood restaurant Reef).
The food is great, although I'm ashamed to admit I only tried the pizzas and a banana split! Though in my defence Brazilians don't cater much for vegetarians.
The service is also very good, the waiters are very friendly, you feel as though you've made a new friend every time you visit! (And I visited there a lot!)
On a Friday/Saturday night they have live music, traditional brazilian Samba mainly.
A good time no matter what hour you visit.
