About Casa das Ostras
Raw seafood done right is harder to find in the Baixa than it looks, and Casa das Ostras fills that gap with confidence. The room is small and the queue outside tells you everything you need to know before you even walk in. Sea urchin and fresh oysters are what people come back for — sometimes the very next day — with scallops and sardines rounding out a short, focused menu where every piece arrives tasting of the Atlantic. Staff help first-timers choose without making it a production. There is wine next door when the mood calls for it.
