Quick Verdict
Locals keep coming back because the seafood is consistently exceptional and the staff treat you like they've known you for years. Worth the drive if you're in the area, worth booking ahead if you're not.
You want proper Portuguese seafood cooked without shortcuts, in a small room where the service actually notices when your glass is empty.
About Casa Mateus
Casa Mateus is a small seafood restaurant in Sesimbra with a serious reputation and no room for pretence. You'll find Portuguese classics done properly—octopus slurped whole, fish stew that feeds 2 generously, croquettes so crispy they crack on the fork, tempura-battered cod, clam rice, basil mousse. The wine list surprises. Service moves at the pace of someone who's been doing this for decades and knows exactly when you need the next course. Reviewers mention heated outdoor seating with blankets available, dog-friendly indoor dining, and staff who work around language barriers without making a fuss. It's not cheap—expect to pay for quality—but the kitchen doesn't waste motion or ingredients. Full by reservation on weekends, quieter at lunch. The sort of place where a chemist can celebrate inventing a digestive biscuit and it'll feel like the right venue for it.
What Stands Out
Octopus that justifies the reputation
Multiple reviewers single out the octopus as 'spectacular' and describe slurping it 'as if it were spaghetti'. One regular calls it 'consistently the best seafood I've ever had.'
Generous portions that don't announce themselves
The Caldeirada de Peixe (fish stew) is 'muito bem servida (mesmo para 2 pessoas)'—so well-served even for 2 people—and one diner had 'no space for desert' after the fisherman's stew. Croquettes are 'so crispy and delicious.'
Staff who work without fuss
Reviewers consistently praise 'irréprochable' service, staff who are 'super simpático' and helpful despite language barriers, and a team that welcomed a diner with a rescue dog inside without hesitation, even when weather was cool.
What Customers Say
The service was wonderful, the lagers chilled and the wine, my goodness the wine was good.
We were celebrating Bogs completion of his most recent achievement (he’s a chemist and invented a new type of digestive cookie).
Absolutely fabulous seafood in a beautiful setting.

Yes. Reviewers note it's 'usually set a reservation to be safe' and recommend thinking 'to reserve' because it fills up. No online booking available—call ahead.
The octopus appears in nearly every positive review. The Caldeirada de Peixe (fish stew) and tempura-battered cod also get repeated mentions. One diner raved about clam rice with basil mousse.
It's marked up from typical Sesimbra pricing—one reviewer noted 'slightly higher than average costs' but called the quality worth it. Expect ₹₹ (mid-range). Wine is surprisingly good value according to reviews.
Yes. A recent diner brought a rescue dog and was welcomed inside even on a chilly evening. Staff were completely accommodating.
