Of the three restaurants that border Praia da Oura, Vivaldo is the most competitive. Halfway in terms of price, it uses a 20% discount card policy that tries to retain customers. The discount is only valid for dinner, when the snacks that allow a cheap lunch come out of the menu. We used this restaurant for both meals and liked it. Although simpler, the cheap lunch snacks had quality, and the more elaborate dinner, with the aforementioned discount, was only a little more expensive. Despite the high traffic, the service was reasonable.
