The waterfront of Santo António de Lisboa is where to eat oysters in Florianópolis. Santa Catarina is Brazil's oyster capital, and this west-coast village is the traditional centre of the trade — the farms are visible from the shore. The restaurants here serve them fresh and simply, typically with lemon and a chilli-based hot sauce. It's best at lunch, when you can sit outside with a cold beer and watch the fishing boats go past.
