Do NOT recommend it. Please try another place. Poor staff service and salty overpriced food.

Good: We were a walk-in for 2 adults around 5pm on a Thursday in Oct 2024, which the host happily took us to a table near the beautiful window view. Seafood soup was light and loaded with shrimp chunks at the bottom. Views were beautiful.

Bad: It went downhill after we sat down at the table.
-Staff was disinterested and rude from the start
-Our 1 dozen oysters meat was NOT cut from the shell and had lots of shells. I understand a little shell is expected sometimes but to charge 17,50 euros for 6 with this experience is terrible. See photo.
-Octopus was extremely salty where we had to down 2 large bottles of water. Lemon juice only helped a tiny bit.
-Fried hike was extremely salty too, even taking the fried skin off
-Staff never asked us for drinks and when we raised our hands to ask for water, they made humorous actions to mock me. I wanted to take it as humor but it was uncalled for from how we've been treated
-Waiter never asked how our food was
-Waiter offered the table next to us a stand for their hats and purse but never offered us even though we came first. We had 2 hats, a shopping bag, and 2 purses
-We asked the waiter for the check and asked if we pay at the table or in the front and he rudely said the table duh
-Shrimp rice tasted like seafood rice with actual rice grains like the appetizer. Fortunately, it tasted fine and not overly salty like the other items we ordered.

Excellent meal, very fresh and great views and atmosphere. Would suggest not to take the seafood platter that they seem to suggest for everyone. Seems like an easy job for them in the kitchen. You should try to order a la carte a variety of dishes.
Well worth it.

Absolutely a stunning seafood restaurant on the cliff over looking Cascais. The food was reasonable priced for a share platter and gave us a good tasteful insight into the Portugal seafood. Staff are great, they explain everything the best they can and bring you out the seafood options. Plenty of options and the sunset over the ocean is amazing. Well worth it!

The service is excellent, kind people paying attention to details with excellent wine suggestions. Food wise it is gorgeous (only eaten fresh products directly from the ocean). Definitely a establishment to discover in the region. Thank you to all staff for this unforgettable experience! I will definitely come again.

First visited in 2016 and remembered the meal so much that couldn't wait to come back! Incredible selection of fresh seafood and fish, on display that you can select.  Highly recommend the fresh prawns starter was phenomenal as were the seafood rice and fresh turbot sharing platters. Waiters are excellent, orchestrated perfectly it is amazing to watch how coordinated they are during a very busy service.
The glass terrace / conservatory is enclosed with panoramic views over the sea, they can't guarantee a table but you can request it.
Highly recommend the journey if you are staying in Lisbon or nearby.
