Nice place run by nice people. The food was excellent - it's charged by weight, I guess some BRL 37,00 per kilo.
One of the few restaurants I saw in Brazil that the soda cost more than the juices - which are sold by color (green, yellow, red etc).
The ambience is very nice - just downstairs of a nice house, some four or five blocks away from the beach. If you're lucky, you can get some acerolas right from the tree.
