Mar do Inferno

A trip to Boca do Inferno often ends with a camera facing the Atlantic and salt on your clothes. Mar do Inferno sits beside this rocky stretch of Cascais and says on its website that it has been a family business for 48 years. Its terrace and dining room face the sea; the kitchen centres on fresh grilled fish and a wide selection of shellfish. This is not an informal beach stall: booking and budgeting for a mid-to-high-priced meal are part of the decision.

The restaurant presents the catch of the day, shellfish and some meat, with grilling at the centre of the menu. Many visitors write that they value the location, views and freshness of particular products; recent critical accounts include dissatisfaction with the preparation of some fish and a terrace reservation that was not honoured. These are individual reports, not proof of a general practice, but they are a useful reason to confirm the table type and booking by phone. For the bill, ask about weight and price per kilo when ordering whole fish or shellfish sold by weight.

The official site gives the address, phone number and reservation option. Service starts at 12:30 and the restaurant closes on Wednesdays; its Portuguese and English versions differ slightly on closing time, so confirm your sitting. Boca do Inferno is a few steps away, and the old town is reachable along the coastal walk. If you prefer a fixed per-person price and a sequence of dishes served at the table, Baía do Peixe offers fish and shellfish rodízio; Mar do Inferno suits diners who want to choose à la carte and eat with a sea view.
