The existence of one of Lisbon’s best fish restaurants has been a closely guarded secret for more than half a century. Its name is “Último Porto” (the last harbor). Now that the secret is out, we might as well confess everything.

The restaurant is tucked away in the corner of one of Lisbon’s harbors (Rocha do Conde de Óbidos). It is not a glamorous place. But for fish lovers it is heaven.

There are tables inside and an esplanade surrounded by containers that is very pleasant when the weather is warm. It is easy to park and the walk to the restaurant is beautiful with the river in front of us and the city on our back.

“Último Porto” opens only for lunch and it is always full of locals. Grilled fish is the main event and the stars of the show are the “salmonetes” (mullets). Their skins are colored with yellow and orange hues, their flavors as bold as their colors. But, there are many other great choices, from sea bass to codfish.

Many restaurants showcase their fish in a refrigerated display. Others bring a fish platter to the table so that customers can choose what they want. At Último Porto, the fish is treated like a work of art—shielded from light and protected from the elements. It only leaves the refrigerator to go to the grill where it is cooked to perfection. It is this care that makes the last harbor our first choice for grilled fish in Lisbon.

Último Porto is located in the Estação Marítima Da Rocha Conde d’Óbidos, tel. 21 397 9498. It only serves lunch and reservations are a must.
