About Casa Mateus
Casa Mateus is a refined Portuguese seafood restaurant anchoring Sesimbra's dining landscape with a 4.8-star rating across 2516 reviews. Guests consistently praise the octopus, fish pasta (a stew-based dish with macaroni), caldeirada de peixe, and tempura de bacalhau—each executed with attention to ingredient quality and careful plating. The wine list earns particular recognition, complemented by an excellent coffee and dessert programme (chocolate and salted caramel mousse features prominently). Service is characterised as impeccable, sympathetic, and attentive; the owner personally checks tables. The interior is described as cosy and intimate with a modern twist on traditional Portuguese cooking. The terrace is dog-friendly with heaters and blankets available, and the space accommodates wheelchair access. Reservations are strongly recommended, as the small venue typically has a queue. The atmosphere balances casual warmth with a contemporary edge, making it equally suited to couples, families with children, and solo diners.
