Cascais, once a humble fishing village, has become one of Portugal’s most refined coastal destinations — where seafood is both a tradition and an art form. From elegant oceanfront dining rooms to lively market halls, the town offers some of the finest seafood in the country.
Here are the five best seafood restaurants in Cascais, along with a very special new arrival from one of Portugal’s most celebrated chefs.
1. Mar do Inferno
Address: Avenida Rei Humberto II de Itália, Casa das Choupanas, Boca do Inferno, 2750-800 Cascais
Website: mardoinferno.com
Perched above the dramatic cliffs of Boca do Inferno, Mar do Inferno is a Cascais legend. Family-run for generations, it is loved by locals and international visitors for its vibrant atmosphere and unmatched freshness. Scarlet shrimp, spider crab, clams, and grilled lobster are perennial favorites.
This is the kind of restaurant where seafood is served generously and without pretension, yet always with excellence — making it one of the most authentic experiences in Cascais.
2. Furnas do Guincho
Address: Estrada do Guincho, 2750-642 Cascais
Website: furnasdoguincho.pt
With panoramic ocean views and a reputation for elegance, Furnas do Guincho is a showcase of Atlantic dining at its finest. The menu highlights Portugal’s maritime bounty with dishes like octopus rice, grilled sole, and goose barnacles, all accompanied by an exceptional wine list.
The dramatic floor-to-ceiling windows make dining here a sensory experience — a harmony of sea, cuisine, and atmosphere.
3. Porto Santa Maria
Address: Estrada do Guincho, 2750-642 Cascais
Website: portosantamaria.com
A true Cascais classic, Porto Santa Maria is synonymous with refinement. Over the years, it has hosted royalty, celebrities, and dignitaries, earning a reputation as one of Portugal’s most prestigious seafood destinations.
Highlights include oysters, tiger prawns, and lobster rice, each prepared with understated sophistication. Combined with impeccable service and ocean views, Porto Santa Maria is an experience of timeless elegance.
4. Monte Mar
Address: Avenida Nossa Senhora do Cabo 2847, 2750-374 Cascais
Website: montemar.pt
Set along the wild Guincho coast, Monte Mar balances tradition and contemporary flair. Its terrace, overlooking waves crashing against the rocks, is one of the most sought-after dining spots in Cascais.
The restaurant is famed for its sole with coriander rice, but the menu also features a wide array of seafood classics that are perfectly executed. For many, Monte Mar represents the essence of refined yet relaxed Atlantic dining.
5. Restaurante Marisco na Praça
Address: Mercado da Vila, Rua Padre Moisés da Silva 29, 2750-437 Cascais
Website: marisconapraca.com
Inside the bustling Mercado da Vila, Marisco na Praça offers a more casual, market-fresh experience. Guests choose their seafood directly from the counter — oysters, crab, clams, or lobster — and it is cooked to perfection before being served.
The lively market setting makes it a favorite among locals, while the quality rivals Cascais’ most elegant dining rooms. It’s a must for those who love simplicity done exceptionally well.
