Signor Sassi by San Carlo - London

My favorite Italian 🇮🇹 restaurant in London 🇬🇧 for over 20 years. Elegant atmosphere, excellent service, and truly authentic Italian cuisine. A timeless classic that never disappoints.

Amazing experience, highly recommend the lobster spaghetti. This dining experience, made me happy. From service, food quality and quantity. The Ambiance was exceptional. Love this restaurant. A piece of Italy in London.

I recently had dinner at Signor Sassi in London. The restaurant has a nice atmosphere, and the staff were polite and attentive throughout the evening. They were also accommodating when it came to dietary requirements, offering several gluten-free options, which was very helpful. The food was of good quality and well-prepared. While the prices are on the higher side, it’s clear that the dishes are made with care, and the ingredients felt fresh. That said, the cost might not make it a place you’d go to every week, but it does work well for a special evening out. One thing I noticed was the lack of background music. The space itself is pleasant, but some subtle music could have helped create a warmer atmosphere and made the setting feel a bit livelier. Overall, I would say that Signor Sassi offers a reliable dining experience with good food and professional service. It’s not inexpensive, but for the quality and the service provided, the value is fair.

The Penne Arrabbiata at Signor Sassi is still one of my favourite dishes, perfect every time. I also love the atmosphere, and the service is always great. Also, try the pistachio cake, tried it via recommendation, it’s fantastic.

The manager was super lovely, spoke Portuguese once he saw we were a group of Brazilians, was very friendly and patient and recommended great food. All staff were great, food is delicious and the atmosphere was pleasant and fun. Definitely coming back soon.

This has been our neighborhood Restaurant for many years but this year we’ve been coming here and the food is really very bad. Milanese overcook, pasta, overcooked, meat bad, service unattended and always with mistakes. We are sad because this used to be our Neighbourhood restaurant where we used to take our friends, but I guess not anymore.

The prices are high for the quality of food. The pasta was bland, chicken just okay. Not worth the price, especially with both a cover charge and service charge. The service from the staff who attended us was okay.

I would recommend Signor Sassi any day! The food was absolutely amazing—not a single fault. The service was impeccable, and our server Stefano was so patient and attentive. The dishes came out quickly, fresh, and full of flavor. And the dessert… wow. My favorite was the crème brûlée — a solid 10/10. Honestly, everything was perfect.

Dropped in for lunch while taking break from sopping at Harrod's. Food and service were superb with white linen treatment and super efficient wait staff. Price was worth the first class treatment received. Very glad we made the stop.

Service starts with some complimentary olives, parmigiana cheese which was stale, and some decent bread. The mozzarella in corroza was barely warm, the crust was tasteless, and the sauce was completely lackluster. The Sassi salad was good. Their signature dish is listed on the menu as spaghetti with lobster. I ordered it and the waiter looked perplexed. I said it again. He said lobster spaghetti. I repeated spaghetti with lobster again to annoy him. He corrected me again. I pointed to the menu. He processed for a minute and replied "the guy who does the menu is new blah blah blah" , which isn't true because it's not a daily printed menu, I assume trying to be funny. The dish itself was pretty good. The pasta was better than the tough lobster. Our friend ordered spinach in her best Italian accent"spinachi!", and he replied "spinach" it came out cold. She had the Dover Sole, which was as thin as tracing paper, and the review was "it wasn't great, it was fine, it wasn't fishy".

Our first stop in London was to eat at Signor Sassi, which is known for their Italian food all over London! It is a favorite of many of the locals, and my dad insisted we try it out. On the walls of the restaurant, you can see all of the football players and managers that have been through: including first is no Ronaldo, Fernando Torres, Jose mourinho, etc. I got the spaghetti con gamberoni piccanti, which was a light seafood pasta that was pretty good. All of the ingredients tasted really fresh, but the pasta didn't seem to be handmade, which was something that I was expecting. My dad saw the pasta romana on the menu and asked if they could do a spaghetti amatriciana instead since they had most things on the menu, but unfortunately it did not come out as was hoped, and came out more of a spaghetti romana instead. Lastly, my brother got the spaghetti lobster, which he said was very good! I think the spaghetti lobster would definitely be worth to get, but the other two disused I would never order again. The service was also very much quality throughout the evening! Definitely a cool place to check out for its food and history.

The only good thing about this restaurant are the reviews. Mediocre food served by staff dragging their feet. Prices are reasonable for London but food is bland in spite a very ample menu.

This was a very bittersweet experience, on that called to mind Proust's "Remembrance of Things Past," since my family used to live across the street from this place when it was Les Trois Canards, or what we called "three ducks," and it was our home away from home for super dinners for any occasion, or no occasion at all. The owner of the Three Ducks sold the space in '84, and these guys moved in. I haven't been back since, but on a recent trip to London, I figured I should hit the joint for a meal for old time's sake. And I'm glad I did. The menu is extensive, and it's not cheap. But the setting and service are terrific, and the food was pretty darn good, so I'd say value for money received, at least from my POV. I had a cocktail, a shrimp dish, and a salad, along with a glass of wine. I was drenched in memories of the Three Ducks - not the same experience, but one that had me thinking I'd happily visit the place again on my next London trip.

Signor Sassi is a total tourist trap. Service is friendly but staff is busy and non-attentive. The biggest problem was that the food took at least 45 minutes and when it finally came out they messed up our order and forgot a few items. Nobody apologized. Ambiance is very rushed and cramped, and staff constantly bumped into my oddly place seat. Food is average at best. Think Olive Garden but at 5X the price. We were so disappointed and will not return.

We enjoyed a delicious meal, I had the lobster ravioli and it was excellent. My wife had the veal scaloppine and was thrilled. We shared the pistachio pie. Very good. We would highly recommend this place.

This place has been around for ages and it seems they are a family of restaurants and have sister restaurants even in Bahrain and Qatar! They also have the sister restaurants around England in Bristol, Birmingham and Manchester as well. Also in the heart of Knightsbridge so good after or ore-shopping. The food is tasty and quite authentic Italian and so not yet affected by modernisation which is always a bonus to have Italian that actually tastes like you're in Italy! Service is a little slow and they are not as attentive as they were in the past. Also, when I booked I did mention we were celebrating a special occasion and they did not go out of their way to acknowledge that and it was ignored or forgotten! The bread tasted a little stale from the basket and hence not 5 stars as they don't top that up either which they used to in the past. They also charge the £2 per person cover charge so everyone is prepared in advance for that.

My friends told me this restaurant is really good, especially the lobster pasta. So I just want to try and have a good dinner with my bf. we tried crab salad and scallops on spinach as starter, and we think scallops on spinach is really good with black pepper. And lobster risotto and pasta are both good,worthy to have a try. I really like the dessert in the blue plate, it tastes like a milk custard, like it!!!

For a person from Milan it's like opening a door and finding yourself at home... I went for dinner with two friends and we had some olives and parmesan to warm up and fish ad main (shallots with bread crumbs and pescatrice - both delicious!) Coffee is also good! Some limoncello and chiacchiere (typical carnival Italian pastry)... I would definitely recommend this place!!

BEST SPAGHETTI!!! The tomato sauce is soo good. I was surprised I liked the lobster spaghetti and prawn spaghetti (spicy w/capers) as much as I did since I've liked both less as I've gotten older for some reason. The waiter mentioned the chef was using (I THINK) Marzano tomatoes which are evidently the best. Fantastic service, too. They are old-school Italians and make you feel at home!

This was the restaurant that finally converted me to loving olives, prior to that I hated them with a passion. Aside from that I rathered enjoyed my time here. The service was great and I got myself a nice Italian wine. The décor in here is wild with a acid trip LSD swag but I think that adds to the charm of the restaurant. I went during December so I'm not sure if it was suppose to be Christmas decorations? I got myself the lobster risotto and Mt friend got the fettuccine. Both plates were good and I left a happy camper.

Found this place cramped - had a series of issues here including our main course "ticket" for food didn't print in the kitchen leading to 45 minutes after our reservation, we ate. And there was no sense of apology when they forgot to heed allergies or forgot to serve portions of the order. The food itself was hit and miss. Some was ok and some was good. Pasta pomodoro was good but fettuccini wasn't special. So I'd say this place is chaotic and not worth venturing into.

Came here for lunch upon recommendation from a friend who ate here a couple years ago. Looked like a solid choice from the outside because it was packed full of people. We went in an were greeted by a friendly host who took our coats and seated us. The menu here is quite extensive, but we finally made some solid choices. We started with the Antipasto Romano which came with traditional roman antipasti of salami, parma ham, artichoke, olives and fried pecorino cheese. Can't go wrong with this. For mains, we ordered a meat pasta and fried calamari, scallops, etc. I wasn't too impressed with the pasta (sorry, the name of it escapes me). Of course, the fried seafood mix was very good. Service was lacking here. They were very slow with bringing out water, bread, the food. Although Signor Sassi is a decent place for Italian, there are many more places I'd rather go to.

Chicken was so flavourful - tasted all the lime, spices and olive oil at the same time, super tender even though it was chicken breast. A lot of fresh seafood just sitting on top of a huge bucket of ice by the front door - how cool! Desserts were really good too - tiramisu had strong hints of coffee, yum and the profiteroles were SO good. so was the chocolate mousse and the blueberry gelato. Pretty crowded in here though so if you're looking for a quiet place, this is more of a loud crowd with people speaking in italian and waiters looking like they're straight out of an italian painting - moustaches and all haha

It is next harrods it so daaaaam goooood Italian food , order lobster spaghetti , ravioli shrimp, grilled salmon wasn't that impressive . I will come again it is so good.

What a phenomenal Italian restaurant! My wife and I had a wonderful window side table last night and the service, presentation, noise level, and of course the food, were all wonderful! I felt like I was in Italy but we were on a quiet side street in London! Highly recommend by this globe trotting couple who crave excellent Italian food.

Previously run and I believe owned by Mario of Scalini fame, this restaurant is tucked away of a fairly grubby side street of Knightsbridge but it one of the best. It has a loyal fan base and is used a lot by Italian families and a fair share of celebrities and sports stars - just look at the pictures on the walls. A very well tried and tested formula that a)works and b) is very good and c)good value for money. Menu doesn't change but it is that good that it shouldn't and a warm welcome is always assured. Food is typically Italian and I have never had anything like a bad meal in there, in fact it has always been top quality. Waiters are always happy and they sign a lot which is always funny and adds to a great lunch or dinner. Please make the time to go and eat here, it really is good.

Always a plus Whenever you think of proper pasta and decent Italian food , it's the place to go You need to make a booking as it is always full Love their truffle special menu A must try is he gnocchi truffles

Maybe it was because my expectation was too high. Nothing is special about their food. For the main course, we got the lobster risotto and spaghetti,which are supposed to be their signature dishes. However, both of them were disappointing. Service was terrible. We were seated in the corner and it always took them 5-10min to come and serve us. The bean salad and tiramisu were average as well.

Lovely warm place to had fantastic food enjoy the real taste of Italian food, friendly staff that work hard to satisfy the customer

I was really looking forward to trying this spot with a great location near Harrods I was expecting a lot. The place was filled at 9:30 and all the servers were Italian made me think it was even more authentic. I was greatly mistaken! The food was so basic and very low quality and fines put into the dieshes. The pastas were all bland (we got the alfredo and puttanesca) I would not ever recommend this to someone. The service was excellent hence my rating.

Great food - on spot, materiel really fresh. Love the Risotto Signor Sassi, very delicious; desert is amazing Service is a bit on the slow side - but waiters are really nice and funny P.S great location - just across the street of Harrods

If I could give this place zero stars I honestly would. The service here is beyond unprofessional. I can't believe this place even gets any business at all. We had a reservation tonight for 9pm and were seated at our table. A couple of minutes later a man who happened to know management at the restaurant walked in and decided he wanted our table. We were then told we needed to get up from the table we were sitting at. When we confronted the manager instead of being professional and helpful he decides to get angry and starts yelling "bloody hell." What kind of a classless establishment is this?! How can it be acceptable to seat people at a table then remove them because another customer "doesn't want to sit upstairs"? DO NOT WASTE YOUR TIME OR MONEY HERE!!!!! Go somewhere that has staff and management that know what professionalism and class are.

It is such a delicious Italian place! The service is great and the food is full of flavor. My husband ordered the lobster spaghetti and it's truly a presentation! I ordered the mushroom risotto and it was packed of flavor. They used a few different mushroom varieties in the risotto and you can definitely tell. We ordered the ravioli also and no complaints there. The staff was attentive and our food came out really quick and it was super hot. I would definitely recommend going here!

Quaint place, great customer service with delicious food! It is a lovely little hideaway.

It claim it's the best lobster spaghetti. I disappointed. And oyster is not fresh at all. And they charge 10 Pounds on hot water without noticing us. That was soooo funny.

This is a rubbish restaurant. All the staffs are too busy to service the guest. They don't care the guests at all, but they limite the time which guests can sit down there. Even, the staff came to blame us that we stand up after long time waiting and without any services. The space of the restaurant is so narrow that you can't breathe. We didn't enjoy our food at all. Honestly, I have to say that was the worst experience I had after I lived in London four year!

The best spaghetti carbonara around!!! My favorite restaurant in London. Everything I've had has been amazing

Great authentic Italian food! This little gem is tucked away in an alley and was a little difficult to find. However, once in, you are greeted by warm staff members who take your coat right away. The food was delicious. Nothing was over-cooked or anything. The calamari particularly was delicious. The ravioli dishes that we tried were also excellent and full of flavor. The lobster sauce was beyond amazing. Would definitely come back here

A Delightful Respite We found this little gem on a side alley across the street from Harrods. I ordered the grilled salmon with dill sauce and sautéed spinach. It was perfect! My daughter ordered the fagoli soup and the eggplant rotini. It too was delicious. The service was efficient and quite "city"'like, not overly friendly. The receptionist on the other hand was warm and gracious. An added treat was the Galani they served as a final treat. The prices were reasonable and the atmosphere very inviting.

The restaurant has a friendly staff and a good atmosphere, especially for dinners.

Excellent Classic Italian food in the center of London! Definitely recommend as it will not disappoint.

Amazing location with an outstanding food. Service is good and quick, I never tried it for lunch (not sure if they do). Dinners are always booked so make sure to suit your self! Seafood are quite taste and starts as usual are perfect.

Amazing food and amazing people very friendly the fettuccine was absolutely amazing with potatoes and scallops I would highly recommend those dishes

One of the best Italian restaurant just 2 min from Harrods. The food it's absolutely amazing. Service almost perfect. Waiters always happy . Necessary booking . Desert absolutely amazing all the time

Amazing food ! Finally found a place where the staff is trained for, and know what they are doing. Experienced staff

A group of us decided to try Signor Sassi and I have to say it was the perfect place. The food was exquisite, service was very friendly and helpful and the atmosphere was exactly right for us. All of our dishes were very tasty and presented well. Great evening!

It was a bad experience , we paid 93 £ for a small piece of meat and a sea bass dish , coke and lemonade it doesn't deserve its price .. A large plate with a small piece of meat on it , if it's delecious it's ok , but seriously it's less than our expectations , I hate this kind of restaurants plus , they r not friendly , we were ignored when we asked to change our table ,,, Will never try it again .. A very bad experience : (

so i have one week left in london, and i'm trying to clear out my bookmarks! my friend ck has been RAVING about the lobster spaghetti since i've been here, and we finally made it a point to go before my return to the states. the lobster spaghetti was amazing, and we also had the spicy spaghetti w/ prawns. both were fab, and i scarfed it down. even the signor sassi salad was delicious. so why the 4 stars? service here is odd. the guy taking our order was pretty rude, and then we had an overly attentive and flirtatious waiter. it definitely made for an interesting experience.

We had a reservation for 2 at 9:30pm. We walked in right at 9:30 and they asked us to wait upstairs for our table to be ready. Once we sat down it was 15-20 minutes before anyone helped us. Once we finally received our drinks it was another 20 minutes before our waiter came back for our food order. The food came out quickly but under cooked, it was also flavorless. I sent my pasta back and just asked for a medium-rare filet, it was also flavorless. Very disappointing.

Food excellent... Loud yet friendly atmosphere. Attentive service. A bit hard to find, but enough off the beaten path that not too touristy although just across from Harrods.

Best fettuccine Alfredo in London! Service was very good. A little pricey though for two plates of pasta(meatless), two cokes and a dessert was over 60 pounds. Didn't understand what the cover charge was for.

What a lovely restaurant. Service was wonderful. The house salad was huge and nicely put together. We had the veal and a pasta dish and both were tasty. The tempo of the meal was refreshing.

food was good & fresh. service was sarcastic but on top of things. prices are decent but can be on the high end. reservations are a good idea. will definitely go back to try other items on the menu.

I feel an obligation to write a review. I have to start by saying the pasta here is one of the BEST I've ever had. Everything was soooo good. The chefs special trio pasta would be my choice next time. I was very jealous of the people that ordered this at our table. The bruschetta with tomatoes was so tasty we had to ask for more like animals. Toasted to perfection. Yes, the service is not the best but I think that's their charm? It's not bad. Go with friends and enjoy the food and company. The food is that good that nothing bothered us, quite frankly. This will be the first place we go to on our next trip to London.

The food here is always good italian food. Nothing that will blow away your tastebuds, but good. The pasta is always spot on. The desserts, unfortunately, are not of the same standard as the starters and mains. So perhaps having dessert somewhere else is a good idea (if dessert is as important to you as it is to me!) Also, the service here leaves alot to be desired.

nice food. but after placing the order, we waited for nearly 1 hour to get our starter. they said there's someting wrong with their computer but other tables all get their food on time⋯⋯

All around, excellent food. I would come back in a heartbeat. Great Italian food in the heart of London. Thank you for being a great host Carman.
