    Tiny mackerel
    Peter D.

    Solar 31 isn't really much to look at from the outside. It's a fairly casual neighborhood spot with what seems to be a lot of regular clientele. The only notable thing there being there was a loud man whose shirt seemed to unbutton at the same rate he was drinking, and it was fully open and he was barechested by the time we left. That hero aside, Solar 31 does have some of the best seafood I've ever had in my life. They can lay claim to the best bite I had during my entire trip to Portugal (hotly contested), which are the tiny, perfectly fried, deliciously salty mackerel. I couldn't believe how tasty these things were, and how powerful I felt just throwing an entire fish, head, tail and all, into my mouth in one bite. I was like a sea lion. I would gladly have done tricks if my wife insisted, just to get another. (We ordered another plate of them though, and no tricks were necessary, just a nominal fee.) Although the mackerel (cousin to the sardine, if you asked our waitress) deserve top billing, everything we ate here was a winner. We had octopus and several kinds of fish. And of course, lots of green wine. Also excellent sangria ordered by our wives, who had finally reached their vinho verde limit. Our server was a no-nonsense gem whose deadpan hilarity made our meal even better. When my friend asked about the size of a certain fish, she just brought it out and held it next to his face. I hoped she was going to slap him with it, but no luck there. When we asked what the incredible sauce that came with our prawns was, she looked at us like we were idiots and said, "Prawn sauce." Basically, this was one of my favorite meals ever.

    Solar 31 is renowned for its seafood and it did not disappoint. They have the seafood on display and show it to you before they cook it, still alive and kicking. My favorites were the raw oysters, the crispy mackerel, and the crab. They cook some of the crab meat with the roe into a creamy dip and serve it to you with toast chips. It was such a unique way of eating crab!

    Attracted to this restaurant because of its food, and central location, despite what others have said was a sketchy neighborhood (not), we were glad to dine here for lunch. A smallish restaurant very well served by two staff in the dining room. Décor was pleasant and inviting. Food was delicious. Service and value were great. We enjoyed (all prices Euro): Small fish grilled (Peixinhos), 15; Octopus (Polvo), 29; and black swordfish (Peixe Espada), 25. All were thoroughly enjoyed. We could not eat it all, but we tried (or at least I did). We've enjoyed octopus in numerous countries, but we've never been served a whole octopus. Very tender. The swordfish was flakier than what we have in the U.S., yet also very tender and flavorful. The waitstaff was very accommodating in allowing us to taste numerous wines before we ordered by the glass. All were very reasonably priced. Total bill was Euro $ 92.30. We definitely recommend and would return.

    Crab

    I had a reservation at this restaurant this afternoon and was genuinely looking forward to the meal because of the high ratings. I ordered a crab on my own, and the waiter brought a live one to show me. However, after taking it to the kitchen, they served me a clearly dead crab instead -- for a price of €45. Halfway through the dish, I had to stop eating. Some parts of the crab had an awful, rotten smell. As someone who regularly eats seafood, I can easily tell the difference between fresh and frozen. This brown crab had no freshness at all -- the meat was loose, lacked any flavor, and didn't have the plump texture of fresh seafood. It was, without a doubt, the worst seafood experience I've ever had at a restaurant. After I finished, my mouth was left with a strong, unpleasant fishy odor.

    Our last dinner in Portugal and we chose this place. Neighborhood's a little sketch, but no harm no foul. It was odd to find this place tucked away from the visible happening streets of Lisbon. But it was worth the trek and the hunt. Everything we ordered was perfection and it made our memories of Portugal that much more special. The staff was our favorite out of all the great places we dined while in the country. The food and the wine was, again, spectacular. Perfectly cooked, beautifully presented, and tasted amazing. I will miss this place! We were three cousins on vacation. But the majority of the patrons dining were couples on dates. Just a funny observation we made. On our order list: Salad, grilled sea bass, octopus and razor clams. That's it! So simple and delicious!!!

    Reading all of the reviews, I had high hopes and expectations walking into Solar 31. Simply put, our meal here was underwhelming (besides the soup) and I believe this restaurant may be too "hyped-up". The fish soup for our starter was really good, but everything from there seemed to go downhill. The Sapateira reminded me a lot of a crab dip you can get from the states, so it didn't taste like anything spectacular or like you were tasting something new. Also, a personal problem I had with the crab was struggling to crack open the shell - I got bits and pieces of shell everywhere and the restaurant did not provide an empty bowl to put the shells in. The sea bream was good. Another thing I was disappointed about was the price to portion ratio. It seemed like high prices for smaller portions, which I would tolerate if the food was fantastic but that wasn't really the case. I would not recommend Solar 31. Instead, if I could go back in time I would go to tascas or another seafood restaurant.

    Better make a reservation because we tried to walk in at 18:00 on a Monday and it was packed. We had a party of ten and could not get in. They encourage us to come back and so we made reservations for a few days later. I'm glad we made it back. We ended up with twelve in our party. We started with clams and octopus. They only serve seafood, so don't look for poultry, pork, beef or lamb. Every thing was full of flavor and had a hint of Smoke. Some thought the grilled fish was salty, but I thought it was perfect. I am sensitive to the taste of salt. Every was fresh. No fishy or gamy taste. Staff were attentive. Loved that the chef/owner came out to explain how the food would be cooked. I especially like that staff would pick out the bones before serving a fish dish. I hate picking out bones. Lots of people were turned away. It's not a big restaurant so make sure you make a reservation. Have a yummy time. I left full and content. So will you.

    The best seafood that I've had! Everything was fresh and cooked to perfection! Oyster and the crab fat was little too raw/fishy for me but the crab meat was cooked delicately that you want to get into each nook and cranny in finding meat. Only thing that was underwhelming was the bread but the best dishes were the Portugal fish and octopus. Not so picturesque, octopus was the best octopus dish we've had! Flavor was good and the texture was so delicate and mouthwatering that we wanted more! The wild seabass was too big for the 2 of us that they recommended a fish that was only found in Portugal. I do not recall the name but it just melts in your mouth and seasoned perfectly! They strayed away from ordering more but truly wish we could have tried the small sardine dish to top it off. The cooking quality was actually better than Ramiro but I'm sure each restaurant is known for specific dishes. I would definitely come here to get a fish and octopus dish hands down!

    Feel this is more like a hyped up place. Everything seems fantastic but just okay. Oyster - so and so. Clam - good but not amazing. Octopus - sadly a whole octopus not cooked enough and still chewy. Crab - probably good but for 2 people this dish was a bit too much (the creamy part)

    This is the whole fish for two. It was HUGE! Plenty of leftovers.

    Great service and food was very fresh and delicious. Loved seeing the fish on ice as you walked into the restaurant. In a bit of a sketchy looking area, but felt safe. Staff were friendly and helpful.

    One of my favorite dinners during our time visiting. The service was super friendly, and everything (and I mean everything) was out of the ball park. We got the octopus which was very tender, I had the best white sangria of my life, as well as clams and lobster. We topped it off with their version of crème brulee. Definitely what to come back next time.

Pastries de Bacalhau - the crust was not brown enough. May be longer time. The stuffing was flavorful but it's more the cod taste than the flavored mash potatoes which I prefer. I actually prefer the other local restaurant I tried the night before better. Caldo Verde - The potatoe part of the soup is great. Perfect viscosity but the flavor is not. It wasn't salty enough but more importantly is the flavor of the veggies and the spicy sausage they supposed to use that makes the soup taste different. Grilled giant pawns - The flavor of the prawns is not as intense as expected and hope to be. The squid ink pasta also lacked of flavor. That's disappointing. With the prawns, they should at least use the prawn shell to make sauce for the pastas. The pasta was tasteless, didn't even use enough garlic and olive oil to flavor it up. Seafood rice - Another disappointment. They used fish, small mussels and little bit of shrimp pieces along with some bigger whole shrimps and mussels. However, the rice was lack of the true seafood flavor that made from shell fish. They also added cilantro which overwhelmed the whatever left of seafood flavor. The lemonade was not a sweet lemonade but sour. Fyi. It's not fair we just went to another restaurant in the neighborhood and everything was so much better but people should know.

He will talk to you for hours and teach you about food and wine and culture and talk about the history of food and how it came to be in Portugal. I loved it. I learned so much. I aspire, as an American, to learn from and look up to other cultures. I feel very honored to have dined in a restaurant managed by him on our trip to Portugal. I'm going to recommend to our travel coordinator to add this restaurant to the Google map recommendations list because more people need to go to this place - they need more tables, more space, because I'm convinced this is such a hidden gem that should be exposed to the masses to enjoy! We visited several wineries and this restaurant had the best wine - bar none! The fish, a fish I hadn't tried before, was deliciously seasoned, falls apart with the fork, the creamy rice was just divine. I normally will never eat little cherry/grape tomatoes - ever - but the perfect bite of fish, creamy rice, and a tomato was... perfection. The menu is deeply curated; flavors - textures - wines that make sense. You can tell Frederico what you normally like and he 100% knows what wines he has that you will love. The tomato, orange, ham, salad, was absolutely balanced and delicious. I'm so grateful that our first trip to Portugal we got to meet Frederico and dine with these wonderful people who love food and wine as much as us. I'll never forget it as long as I live. You will not be disappointed. Promise.

It was not crowded at all on a Friday night, and I was able to strike up a conversation with fellow diners and actually hear myself talk. That is rare these days.

I started with the chorizo, which you cook yourself right at the table. For my main course I ordered the steak with eggs, and it was excellent. To finish, I had the crème brûlée for dessert, and it was also outstanding. Overall, a truly wonderful hidden gem in Lisbon. I cannot wait to return.
