Hubby's Birthday Dinner - we celebrated my husbands birthday in Portugal this year ! I was so happy to see that Yelp had a presence in Portugal so while planning the trip I started book marking all the cool exciting places I wanted to check out ! Sooo I was so happy to find Restaurante Mar Do Inferno! It had gorgeous views of the Atlantic Ocean and the best seafood ! We made our reservation online before leaving California. It was easy and had an English and Portuguese option. We arrived and once we got there we were greeted warmly and seated quickly . There were all these fresh seafood options that you could pick from in live tanks ! Service was top tier !! Our waiter was funny and very entertaining! He warmed up even more as the evening progressed! We had the best view of the sea and ambiance was lovely ! We ordered the seafood platter - langoustines, lobster, prawns, sea bream, potatoes in a garlic butter sauce !! Everything was SO FRESH!! So delicious !!! Great wine selection especially European wines and cocktails too !! Hubby loved it and we definitely will come back next time we are in Portugal!! read more

Restaurante Mar do Inferno - Fresh catch - Portuguese Near Me - Cascais, 11

I don't think I have ever gotten worse service anywhere. The large man that served us could not have been more indifferent towards us. We watched 2 other tables get seated and nearly finish their meals before we got our food. I am a former chef, so I know what the hard skim on top of our dishes meant - that they sat in the window while he catered heavily to other customers. What a disappointment!! read more

Our group of five had lunch at this restaurant on 25 January. Four members of the group ordered raw oysters, and ALL four became ill afterwards with high fever, vomiting and severe abdominal cramps. The fifth person, who did not eat oysters, remained completely fine. We informed the restaurant promptly and submitted a complaint through the official Portuguese Livro de Reclamações. While the restaurant initially engaged, they denied any connection, requested medical documentation, and ultimately just stopped responding altogether... The whole experience resulted in our entire household being affected all at the same time, causing significant distress and two full days of missed work and school. Our elderly family friend got quite sick, used to be a regular customer there, he didn't even get an apology. We made repeated attempts to resolve the situation amicably and provided supporting documentation of the impact, but no resolution was ever offered (our total bill was approximately €380). Extremely disappointing, recommend to AVOID. read more

The location of the restaurant is great if you are looking for oceanfront dining experience. But don't expect too much of the rest, and be aware of potential attack of the flies. We ordered the Salada, Caril Lavagante, the Pregado Dase, and the Sangrias(red and white). Only the Sangrias was good IMHO. The flies were extremely annoying because they kept attacking our foods. The waiters seemed to get used to it. read more

Excellent seafood, service, views, and ambiance. Located in a very scenic area by the sea. Highly recommend to experience an amazing seafood meal. read more

We really enjoyed this restaurant. The views are amazing, the food and the service were fast and our waiter spoke Spanish which was a relief. The pasta was out of this world. Hope you come and enjoy read more

Excellent view of the waterfront. There were 6 of us for lunch and the service was exceptional. The clams and the fresh cheese were excellent. I would also recommend the sea bass grilled. The wine list was extensive and reasonable for fine dining. Will return on my next visit to Cascais. read more

Restaurante Mar do Inferno - Our lunch wine, really good! - Portuguese Near Me - Cascais, 11

This place seems to be more view/ambiance than anything else~we ordered the seafood rice (basically a paella, so to speak) and red sangria. We both enjoyed our food and sangria, but weren't floored by it either. I'd definitely come back again if we were staying in Cascais, but it was a bit of a hike from Lisbon and didn't really feel worth it bc there are many, many outstanding seafood spots throughout Portugal. The view is the biggest draw here imo and that's okay bc there a lot of ppl who care more about ambiance/decor/views than their actual food...perfect spot for that crowd bc it's something you won't forget! read more

Restaurante Mar do Inferno - Grilled fish and paella - Portuguese Near Me - Cascais, 11

One of the better ocean fronting restaurants on the toad from cascais to Guincho and within walking distance from Cascais old city. You can pay more for a Michelin star but it won't be a much better experience. The wait staff was very flexible. They turned a 2 person in to 1 portion meal at a good price. Outdoor seating to watch the sunset. read more

Worst customer service ever. Let me start by when me and a friend walked in the first thing their server said was do you want to see the menu first before taking a seat, basically saying that we look broke for this restaurant. We said no that we will take a seat and look at the menu. We go ahead and take a seat and 20 min pass and non of the server's attends us. Another couple sits down next to us and the server brings them bread to the table and bring there drinks mind you we've been sitting in our table 20 min trying to get attention from them and none of the server will come to the table. Customer service totally awful. read more

Very touristy. Average food and a very long wait to get it. The "oceanfront" view leaves much to be desired. There are far better places to eat in this area. read more

Really delicious food at first the one fella said they had no room for us and I believe it's the owner or the owners daughter Mariana squeezed us in. Highly recommend this place. A bit pricey but great. I suggest you call for reservations. read more

Excellent food with a great view. Reserve an outdoor table to watch the sunset if you can. Four of us split two two-person platters and felt that it was more than enough food. Everything tasted great. read more

The prices on the menu have no bearing on what they will charge you when you get your check. We ordered a tiny amount, a few soups and a few individual bacalau of 2 eur each, which were supposed to be a total of about €20. They charged me €43. when I complained they insisted that was right and basically I just had to pay and leave. read more

3.25 stars. This restaurant is located near Boca do Inferno (Hell's Mouth) in Cascais. Make sure you get some good views of some incredible landscape before or after eating here. Overall, this is a good restaurant with some very fresh seafood items that you can view yourself before purchase. We actually did not do that which was probably a mistake as there were some very tasty looking items ordered at other tables. What I will say is that the wine selection was good, the clams we ate were absolutely perfect (better than a similar dish at Ramiro in Lisbon) and I thought the sea bream was nice if not a little bland. Make sure to brush up on your Portuguese when you order here or you might get a couple of odd looks/slightly less friendly service. read more

Lovely elegant dining room overlooking sea was marred by a large party of about 25 flies that had apparently made a reservation for the night. They stayed for about an hour into our dinner until they turned all lights fully on. It was very odd that the restaurant staff and other patrons seemed wholly unconcerned about this. I suspect it was not the first night of the flies reservation .Service was barely there . Overall food tasty and reasonable for quantity and quality. We started with fresh crab meat which was a generous portion but unflavored and unceremoniously just dumped in a crab shell .Main course was a massive grilled platter of adequately fresh one whole fish with an entire lobster multiply tiger shrimp mussels and smaller shrimp under 100 euro to share for 2 . Could certainly serve 3. Ended the meal with a horrific lemon pie which was about 90 percent poorly cooked meringue and a 100 percent inedible . Since Cascais is swimming with many other seafood restaurants with no flies , better food and much better service I would not return and am baffled at its high ratings. I suspect it's surviving on its former glory days but sadly I must report these appear long gone. read more

Very nice restaurant right on edge of and overlooking the Atlantic. Came in on a weekday for lunch and seemed like a lot of locals were eating here. Had the octopus which was served in a pan with olives, potatoes and onions. So good. Was only able to eat half and took the rest home. Would come back to this in a heartbeat. read more

This is a seafood lovers heaven. Looks ordinary from the outside but it's really nice once you step in. White table cloths, nice cutlery and china and very friendly staff. I loved this place and would come back here in a heartbeat. There was about twenty of us at dinner and we had a fixed menu comprising of different types of seafood, starters and dessert. There was nothing that I did not like. Grilled sea bass for main and shrimps, tiny lobsters and clams for starters :-) yummm The sea bass was grilled to perfection and the cold seafood starters were fabulous. A few of us ended up emptying all the plates on the table with leftovers lol Staff were very attentive and we had two waiters for our table that came around regularly to top up glasses and check up on us. All in all a fabulous experience :-) read more

Delicious seafood restaurant located a few minutes away from Boca do Inferno. The food, service, and ambience were all excellent! It was extremely easy to make a dinner reservation via email just a day prior, and they were super accommodating when we had to change the date AND when we arrived a full hour prior to our set time. Despite our last minute change of plans, they still managed to seat us on the patio (enclosed for the rainy weather) next to the windows so we could have a view of the ocean - which we weren't expecting at all. Definitely order one of the seafood platters for two. My fiancé and I didn't feel like fussing with crab, so we got the Special Platter (75 euros) which came with sea bass, tiger prawns, and lobster with potatoes and vegetables (according to the menu). The actual plate also had several pieces of shrimp. All of the seafood was cooked perfectly! The lobster was so tender and juicy, and had tons of bright orange tomalley (or roe?) to dip the meat in for a layered umami experience. The tiger prawn was also huge and succulent. And the shrimp! What a lovely surprise. It was cooked very well and also came with the head (easily removed), which had tons of flavor to be coaxed out. That was probably the most flavorful bite. The sea bass was also extremely meaty and moist. The olive oil with garlic at the bottom of the giant platter served as the perfect accompaniment to all of the seafood, as well as the potatoes and vegetables. It was easily more than enough for two people - you could probably have shared it among an additional 1-2 people if you got some more sides to share. This was a must visit for visitors of Cascais. read more

OMG. This place was a-ma-zing. I had been a bit skeptical, because it was right by Boca do Inferno, and I thought it would just be a thing because of tourists. But some colleagues took me there for lunch while I was there for a work trip, and it was so, so good. We had some local white wine as a refreshment, and a couple appetizers. But the best part was the Polvo à Lagareiro, tender octopus tentacles in olive oil, potatoes and some other bits, that was absolutely delicious. This dish was so flavorful, tasty, and tender. I hadn't had octopus before, just calamari of various qualities, and it was much, much better than I had expected. read more

Wonderful location overlooking the Boca do Inferno. Excellent service and an amazing selection of seafood and other Portuguese specialties. We had sole and octopus, both to be highly recommended. read more

Dang, the seafood was really good here. This place is the place to be if you go to Cascais. We were lucky to get in because we didn't have reservations but decided to drop by since it was a bit late for lunch. The place was full but they had one table available if we didn't mind sitting in the smoking room. We aren't smokers but we really wanted to eat here so we subjected our lungs to smoke and the food was worth it. We ordered the seafood platter plus garlic clams and octopus. Our server said we ordered too much food and suggested we drop the octopus. When the food came, it was a lot but I eat a lot and was craving octopus so we ended adding it back. Everything was delicious and I was very happy I got to dine there. We were also lucky because our server was super nice and spoke fluent English. We were very happy with our dining experience despite having to sit in the smoking room. read more

Incredible restaurant! Amazing service! Absolutely 5 star all around with an amazing view! Many fellow Americans find their way there also, and now we know why! A MUST when in Lisbon! read more

I enjoyed the train ride out to Cascais from Lisbon and how there's a beach just foot steps from the station, Praia da Rainha. The walk from the station to Mar do Inferno had some other beautiful spots to stop and enjoy, including some a little hidden and off the beaten path. As for the restaurant, their whole crab was pretty good. The clams were solid, but I've had better elsewhere and have made better clams myself. I did not like their sangria, which was loaded with granules of sugar. The service I received wasn't the friendliest either. I did sit at the best seat in the house right by an opening out to the ocean. There was something perfect about eating seafood to the sound of the ocean. I'm glad I gave it a try, but I wouldn't come back to this restaurant again. read more

Great restaurant right under a sight seeing destination. If you are going to Boca do Inferno, this is the most ideal spot for lunch. We got the $40 euro seafood platter to share and it was huge! You can probably share this among 3 or 4 people with the addition of some apps. Book a table with a view in advance. Inexpensive gift shop area near by as well! read more

I came here for dinner alone on a weekend trip to Cascais. I arrived early (6pm) knowing that I didn't have a reservation and may have better luck early. When I arrived, there was no one at the door but this lady cleaning the floor who proceeded to ignore me when I said hello. Had to walk all the way through the place to find someone to help me. A waiter finally came and seemed annoyed that I didn't have a reservation but sat me anyway. Service was slow and inattentive, unlike what I had experienced in Portugal so far. In terms on ambience, there was no music playing, only a very annoying phone that wouldn't stop ringing and a lot of noise coming from the kitchen. Really weird Food was good, on the pricy side but good quality but don't think I would ever come back here. read more

Delicious food. Our car was broken into outside while we had lunch. All of our luggage was stolen. Watch out.

What a gem, the service was excellent. Waiters friendly and wanting to assist you. Not even expecting a tip. Now to talk about the food. Barnacles, crab, giant prawns, clams and a delicious grilled sea bass. Pictures will tell the story. And don't forget about the white sangria. read more

Stunning views, great food, what more can a girl ask for . We had dinner reservations as it was highly recommended online. We arrived and the restaurant was busy on a Sunday evening. On entry, you see all the seafood on display. Staff were alright, we expected staff to be friendly and welcoming seeing as it's a tourist hotspot. We were offered bread with melted cheese which was unusual but tasty. We ordered the seafood platter for €75/80, it came with veg and potatoes and is one of the best meals ever. We weren't drinking on the night so the total bill was ~€90 Tips: 1. Book in advance - sea view 2. More expensive than most restaurants in Cascais 3. Take a long walk after, stunning views which is a nice spot for a proposal - should you feel inclined to read more

Lunch was excellent. The view of the ocean while drinking white wine having buttery clams that melt in your mouth. The lamb Cheese was excellent. Bread is extra $ but it's great with the cheese and dipping in tag clam juice. The cod was outstanding very crispy and tasty. The curry shrimp is tasty and deliciouse. Ordered a local wine which is superb. Coffee to go and back on the road to old Lisbon. Make sure you visit the local artisan market next to the restaurant. It's a tourist trap but the people are nice and prices are less expensive than the store. Enjoy romantic Portugal. read more

Even though I am not so much into fish eating I must say I really enjoyed eating in this restaurant. The restaurant is sitting on the tip of a cliff right by the rough sea. Coming in to the place it seems like the chef at just come back from the fish market. So much fresh fish and clams and shrimps are lying around next to the kitchen. Seldomly eaten so well in a fish restaurant. read more

Delicious delicious food!!! We were 30 minutes late for our dinner and they still accommodated us even though they were at full capacity. Not one seat was empty and we still got seated and served promptly. The restaurant is still being run by the owners themselves keeping the service at its best! Food was reasonably priced. We ate approximately 1kg of grouper. It came with spinach and delicious potatoes! Would definitely go again to this restaurant! read more
