We happened to look up restaurants on Travel Advisor and this one was highly rated. The outside dining area was appealing but as we walked inside, I was drawn in by the decor - clean, cozy, and serene. Their bathroom was stunning immersed in green tile. We were seated in the back next to a window with a beautiful view. Service was attentive yet unintrusive. We were so hungry and ordered quite a few dishes: Starters: Bread/Butter Olives Foie Gras White Anchovies Prawns with Garlic Main dishes: Caesar Salad (enough to be shared by 2 people) Steak was served medium rare and came with fries Bacalhau - Cod EVERYTHING and I mean EVERYTHING was delicious!! I did not realize that the Caesar Salad came with chicken. It was a meal of its own. However, the steak and cod were the highlight of our lunch experience! The steak was well-seasoned and tender. They made sure it was prepared medium rare. The cod was also tasty paired with sauteed greens and their version of mashed potatoes. Such a beautiful restaurant. This spot is a hidden gem in Sintra - give it some love and check it out.

Unfortunately, it ended up being the most disappointing--and most expensive--meal we've had during our month in Portugal. The experience got off to a poor start. The hostess wasn't welcoming, and when I politely asked if we could sit closer to the window, I was told those tables had been reserved weeks in advance. We had also made a reservation for our anniversary, so that was disappointing. We were seated behind a pillar instead. Throughout the evening, not a single member of the waitstaff smiled. They all looked unhappy to be there, which created a surprisingly cold atmosphere. None of the staff ever came by to ask how our meal was, and no one acknowledged our anniversary. The restaurant itself wasn't nearly as elegant or luxurious as its reputation suggests. Aside from the lobster tank, the décor and atmosphere felt rather ordinary. To make matters worse, our view overlooked a wire fence and a parking area instead of the beautiful ocean setting we had expected. There were also several odd service issues. I ordered a gin martini. They said they were out of green olives, so I requested a lemon twist instead. The drink arrived with black olives and a lemon twist, which was confusing. As for the food, the complimentary bread with the crab pâté was excellent and easily the highlight of the meal. Unfortunately, everything after that was underwhelming. The sea bass was bland and forgettable, and the vegetables were overcooked to the point of being mushy. What made the evening especially disappointing is that every other restaurant we've visited in Cascais has been wonderful. Friendly, smiling staff checked on us, made us feel welcome, and served memorable meals--often at much lower prices. Given Mar do Inferno's reputation and premium prices, we expected an exceptional dining experience. Instead, we left wondering how it has earned such glowing reviews. I genuinely hope management takes a close look at the service, atmosphere, and food quality, because right now the restaurant simply doesn't live up to its reputation.

This spot was decorated with wines on all the walls and a white table cloth feel. We got sat right away and they had menus in English and Portuguese. We started off with some bread butter olives and cheese for the table. Loved the different types of breads in the breadbasket as well as the variety of olives. The cheese was also fresh and creamy and a perfect combination with the bread. We opted for a bottle of verde wine and we got the gambas al ajillo and the fish for two. The gambas came out right away and they were delicious and with a hint of lemon they were a must. The fish for two was fantastic, it was served table side and the sauce that it came in was delicious. Great spot for authentic food and easy to accommodate a group.

Sadly, rhe one item we really wanted Lulas ( Grilled Squid) Rechadas was off the menu. We realized the menu in Portugués versus rhe English menu did not have the daily specials. So with the help of Google translator, i was able to figure out the menu. Our waiter could not take the order, so another waiter came by to assist, i dont soeak portuguese. Nevertheless, order was placed and the food cane out within 15 minutes. Our favorite dish was the grilled dorado fish, nice grilled-charred flavor, served with boiled potatoes and some steam carrots and broco. The beef tongue is melt on your mouth, tender, slice thin tongue beef. The brown sauce add a nice level of seasoning but it does not mask the beefy flavor of the beef tongue with just enough fat in the meat to induce the palate, the french fries for some reason were not as crispy as the fried we are accustomed in the USA. But I noticed the same when were in Greec, we actually had to ask for extra crispy fried- well that will have to be next time. The Garlic shrimp was good but it did not take me flavortown, felt like it could have used more garlic. By the way the Garlic shrimp was more like a tapas size serving, we also order some bread and butter. Unlike in the USA, here you have to pay for bread and butter, which is cant get used to it. The bread was rustic, crusty and cut into small pieces. We did not have dessert because we wanted nata from a store nearby. We. Oticed they haf roasted Pernil with mashed potatoes but that seemed heavy even if we shared it but it did looked very good, as the people next to is ordered it. The house wine was just ok, nothing great but a glass of red with lunch is a good option. We finished lunch with expreso shot. Great service, very clean bathrooms and nice upscale ambiance.

Very consistent as in we enjoyed everything we ordered... other restaurants, our meals were hit or miss around the table. Would highly recommend!
