Le Mercury is an amazing hidden gem in London. The food is delicious, the atmosphere is cozy, and the prices cannot be beat. I suggest trying the duck entree and the poached pear dessert, both of which are some of the best dishes I have ever experienced. Every time I am in London I will be eating at Le Mercury. read more

Had passed this place a lot and never got around to calling in until one night when 6 of us decided to go for food and every where was absolutely packed out around here. With empty grumbling bellys we made it to a really busy looking La Mercury and luckily were able to get a table upstairs. We couldn't believe how cheap the food was, we got a set meal and the food was stunning. We were all well impressed and would definately head back soon. read more

Friendly service and delicious food. And don't be put off if you walk in and it seems full, there are tables upstairs. Will be back next time in the area for sure! read more

The atmosphere, the location & service was very good, the food was excellent, abit on the pricy side for the food on offer though in my opinion. The portion sizes was adequate, good place for a romantic meal for 2!!! read more

Love this spot. A great place to take a date, with its cosy atmosphere and wine bottle candles lending a romantic ambience befitting a French Upper St restaurant! Food is surprisingly good value (mains £7) and imaginative. Ingredients taste pretty fresh and the plate is well presented. Not quite haute cuisine, but still stylish. Staff are ok though not great, especially in peak periods. Choose a quiet time for a lovely evening. read more

Pics@Chopstix2Steaknives http://chopstix2steaknives.blogspot.com/2011/10/le-french-cuisine-eating-at-le-mercury.html Do you like to be tasked with choosing a place to eat or are you one of those who like to leave it to others? For me, I'm happy either way. These two restaurants serving French cuisine were suggested by friends I was catching up with and that I haven't heard of. One was to celebrate a birthday and the other was visiting friends in town. Let's start with a birthday dinner at Le Mercury. It was a cold windy evening and I was walking with a fast pace dreaming of the warmth that will greet me when I open the doors of the restaurant. In I went and was led up a flight of narrow wooden stairs to my table. It was a very reasonably priced menu with all starters priced at £3.95 We ordered a trio of starters starting with the Calamars Fris which is deep fried calamari with home made tartar sauce and dressed French leaves on the side, Beef Carpaccio with capers and red peppers relish and finishing with the Ravioli de la Mer, a crayfish and lobster ravioli with spinach and shellfish sauce. For mains which were all price at £6.95, there was the sea bass fillet with crushed new potatoes and minted pesto, a rib eye steak served with shallot sauce and a Scottish salmon with sautéed spinach and lobster sauce. We all had a great time soaking in the atmosphere and vibe. It can indeed be quite a romantic place. The food may not be outstanding but is decent and with those prices, reflects a good value. An unassuming place that might not reside in your memories for long but will be thought of fondly if this happens to be part of your local eaterie. read more

Extremely affordable French restaurant in Islington. Do not be fooled into thinking they are closed at night, as all tables are lit by only candle light and it looks quite dark from the outside. read more

I'm quite bemused by all the positive reviews for this place. Took a date here and was somewhat embarrassed at how poor quality the food was. For Angel, I was expecting better. read more

Really good simple french food, every dish that came out was really tasty and hit the spot. The special slow cooked beef was superb!

Amor, Amor, Amorthe place screams romance and lurve. Candle lit twosome tables, fairy lights adorning the windows, French waiters, cocktails, champagne, steak the list is endless on why this place is literally the hottest place for couples. Want to know what makes It even better? All choices in each course are the same price so you know you can afford it. Now, I'm not one to endorse the act of polygamy, but if you are a serial dater than this place is perfecto. You can wine and dine your lover and be safe in the knowledge that it won't cost more than fifty of your English pounds for two people to enjoy a 3 course meal with booze a bonus in my (little black) book! read more

We visited this place based on other Yelp reviews while staying in London for a few days. It absolutely lived up to the hype -- fantastic food, good service, delightful atmosphere and at a good price. The starters were 3.95 and the entrees were 7.45. We had the roast duck which came with excellent mashed potatoes, chopped up greens, and gravy. The fresh bread that came with the meal was also great and particularly good for sopping up the gravy at the end. Finally, the best part was the goat cheese salad starter which was seriously the most delicious thing I've had in the last 12 months. This place was great! We hope to go back before we leave town in a few days. read more

I went to Le Mercury {Deuxieme} which is less than 200 feet from Le Mercury and has exactly the same menu. The first thing you notice about the menu are the prices, they are so reasonable! And with each course all dishes are the same price: starters £3.95, mains £8.95 and puddings £2.95, so it is perfect for a group of friends sharing or a date going dutch. And the restaurant had a good mix of groups, friends and dates, so it appears to be suitable for every occasion. Portions are not big, so those with big appetites might want to add some sides which are again very reasonable at £1.95. I had the duck, in fact most of my group did, and it was delicious. The meat was so tender, and it came with a creamy garlic mash and a rich jus. I would definitely recommend. Additionally: One of our party was 40 minutes late, and although they did keep asking us how much longer they thought she would be, they were very good about it. They refilled our (complimentary) bread while we were waiting. read more

The menu is exciting and varied, the food is delicious, the service is friendly. If you want something different, if you want to impress someone or if you want a romantic venue eat at Le Mercury. read more

Excellent food at better than fair prices. The crab salad is bliss!

I really enjoyed this restaurant - have been back again and again and very impressed every time I go there. It's always busy so best to book. Service is good, friendly, efficient. Very good value for money. In fact I'm going back again today! read more

Plumped for Le Mercury having never before been. Pack them in (with little room to move and waiters crashing into my chair) and serve it cheap is the name of the game. Decor is lovely and service efficient so expectations were high. The Brie starter was adequate however the Moulles was excellent, in a delightful creamy sauce which was swiftly despatched. The food went downhill when we received our main courses. The meat of both the Rib Eye and the "special" of the day, not veal or pork but thick slab of beef Weinersnitchel, was inedible and akin to chewing gum. We both left most of our mains and when we commented to waiter on quality of meat we were met with a "would you like to order anything else from the menu", implying we pay for another main. We declined, polished off our wine and left. read more

Have lived around the area for about 5 years and have tried loads of the restaurants on upper street and always come back to this one as my favourite. It is excellent value for money, has a cosy, romantic atmosphere and the food is always delicious read more

I go to both Le Mercuries quite often and I love the food. But make sure to call to book a table, it's usually quite busy.

Food was exquisite, very reasonably priced. Customer service was top notch. Great evening overall.

They were so kind to let us in a hour before closing. The prices were very reasonable. The ambiance was quite romantic even though I was just there with my best friend haha. It's ok. I fell for their duck confit. Perfectly cooked. I was so happy to have a very good first meal in the UK. I also had their beef option but it is nothing that I would recommend. Overall, I recommend Le Mercury. read more

A great little French restaurant in Islington. Food good as is the service. I'm due for another visit I think!

Great food and service is also good... decor a little drab these days.. still a favourite of mine though

The food here is pretty good even for my french friend's standards. The place is nice and bright, the prices are exceptionally cheap and the food is great. Definitely a must try if you are in the area! read more

My starter mussels were tiny, overcooked and tasteless. My mains of smoked haddock was again totally overcooked and rubbery. The side salad was a sorry one, limp lettuce and almost no dressing, boring bread. Someone is missing the main points of cooking here, cheap food does not neccesariry mean bad cooking. I live in Green Lanes were all the Turkish restaurants offer that perfect combination, really affordable, perfectly cooked and timed fresh food, salads to die for, warm fresh bread, all the attention to the details that make a meal memorable. This restaurant is overhyped. read more

My favourite French restaurant in London. I've visited Le Mercury and their sister restaurant, Le Mercury Deuxieme (only a block away!) more times than I can count, and each time it has been flawless. For next to nothing, they serve delicious, simple French cooking, along with a pretty decent wine list. It's usually packed and can have a noisy, boisterous atmosphere, so I would definitely recommend booking a table. I would come again and again for the seafood ravioli starter! read more

You really can't fault Le Mercury for what it is. All starters are the same low price. All entrees are the same low price. And yes, all desserts are same low price as well. It's incredibly cheap, yet still tasty. Probably the best value for money you can find in the area. It does get quite crowded though, so call ahead and make a reservation. And also be prepared for it to be a tad noisy on the weekends, but certainly not overwhelming. read more

Le mercury- je l'adore. Delicious French cuisine by candlelight at unbelievably cheap prices. Be sure to book as this place isn't a very well kept secret! read more

Very disappointed with the service and attitude. Booked a table here for a celebratory meal with my partner and specifically asked for table on the 1st or 2nd floor (ground floor very crowded and people squeezing past table all the time to go in and out of the door). When we arrived the waiter moved another couple from a table right by the door, sent them upstairs and offered us that table. When I explained that I had booked for upstairs, a week in advance, he just shrugged at me and said they were very busy. Needless to say, we ate elsewhere! read more

Great find! It is exceptionally reasonably priced for location, friendly staff, electric buzz over the three floors, good tasty food and mixture trendy of young and old customers. read more

Good food and wine. Cheap prices. Will definitely come back again. Also the ravioli starter was amazing

Can here last night with my wife for an impromptu school-night meal out. Loved the menu, full of hearty French bistro classics. Bread and butter were served immediately and starters were quick to arrive and were very impressive. Soup of the day and lobster ravioli were both excellent and at only £3.95 each, easily a bargain. On to mains, I had the steak entrecôte and was not disappointed. The steak was cooked perfectly, melting apart and tasted excellently rich and beefy. The jus (of which there was plenty for me to mop us with my frites) was also divine. My wife had pork belly which was meltingly tender and our side dishes of vegetables (with rosemary) and frites were also very well cooked. For three courses a la carte with a bottle of red and 2 sides, the lot came in at a little under £50. Virtually unheard of at any restaurant on Upper St, or for that matter in London! Great food, great wine, great atmosphere and great price. We'll definitely be back! read more

I love Le Mercury... excellent food, and a great value! Beautiful atmosphere as well. BUT-- book ahead if you can, always busy.

Decent fine food at reasonable prices. Good service despite being even early on a weekday evening (on that note - booking recommended). Would definitely go again. read more

Veggie dish was reasonable but not hot - food was served far too fast after ordering. Sunday lamb roast was ok, apparently. Desserts were average. Toilets were grim. Overall - disappointing. read more

Excellent value, flavoursome French food. Candle lit for a warm ambience. Perfect for dinner with a partner, to impress without a big price tag, or a small group of friends. With most dishes priced the same its easy to split bill between a group, without any tight fists getting their knickers in a twist over who's meal was more expensive! read more

My favourite french restaurant in London. It is my special occasion restaurant. Great affordable price and amazing food. Their duck and oysters are amazing. I tried almost everything on their menu. Guaranteed a great dining experience with a romantic ambience. I do have to say it can get a little crowded as it can get very busy on weekends. read more

What an absolutely delightful restaurant! Went there with my Mum and sister. Beautifully prepared French food. I had the blue cheese and walnut for starter, with delicious light salad dressing. My Mum had the prawns which she found delicious. For mains I had the sea bass, the staff were so accommodating allowing me to swop one side for another of my choice. Overall food was decadent, decor was elegant, staff were superb, and atmosphere relaxing allowing us to immerse ourselves in wonderful food and conversation. Would highly recommend Le Mercury. read more

I would strongly recommend trying this place. The food is consistently excellent and the price is very reasonable.

Excellent French restaurant that's v.good value for money!Booking usually required

Best place on upper street, great atmosphere and food that does not break the bank (for once a restaurant in London which charges a fair price) read more
