Ate there 3 times during my stay in London. Amazing sea food, top of the line service and excellent atmosphere. Mackerel and Halibut were a delicacy. They are currently my top restaurant in London - though they do not come cheap. Clientle is mostly businessmen on meetings.

As always it`s an absolute joy to dine at 101. The service, food and wine list are excellent. We loved slightly altered sustainable fish menu and king crab and mackerel were our favorite. Our favorite fish restaurant in London for last few years and we are always looking forward to dining again and again.

We've been to this restaurant a few times and it's definitely one of the best seafood restaurant in London! Service is great, and we especially love the wine they recommend to go with the food. Well most importantly the food is always excellent and tasty, chef is very creative in mixing different cuisine!

A wonderful experience. The small fish/duck plates are a perfect lunch option and the rhubarb dessert was just exceptional. The value was good. As one would expect the service is gracious and unhurried. Previous reviewers have criticised the ambience and decor. Its true the ambience was relatively quiet - however I regard this as an advantage as this is a... More

I loved this place, it wasn’t very busy as we went over lunch – but even so I thought the few people that were there together with the staff created a perfectly acceptable atmosphere. As well as this you always had the fact that the window surround meant you could watch the world of Knightsbridge wander by. I found it... More

Very disappointed, everything that had been written about the food is probably true, but the lack of any vibe completely spoilt the experience. The design/layout of the place was not helped by being half empty but all 4 of us agreed it was very poor, service was attentive and the food was pleasant, perhaps it does better when full but...

As a Koffmann's and Apsleys devotee I always found it impossible to resist the temptations in the short walk from Hyde Park Corner and make it to One-O-One...But for once I took a diversionary route and I didn't regret it! At the table we tried the splendid Norwegian King Crab, both simply served cold with a fine mayonnaise, and in... More

The food was amazing- each course beautifully crafted with superb flavours. However, the restaurant itself is horrible- a crime against design. How, in today's London, could anyone have come up with such appalling deco? The room's lack of soul or charm makes me question whether I would return. A shame, because the food was great.

The food at One-O-One is undeniably top quality, fresh and beautifully prepared. Did we enjoy it? Not really. Sometime in the 90's it became fashionable for chefs to produce plates of food that look like abstract paintings, with unusual marriages of flavours and gorgeous little shapes and designs all round the plate. I have sat before many hundreds of such... More
