The Betterment by Jason Atherton is a contemporary dining experience located within The Biltmore Hotel, Mayfair. Luxurious yet relaxed with modern interiors and a menu suitable for sharing, The Betterment is the ideal place to socialise with friends, family and colleagues. The seasonally driven menu features beautifully presented dishes of wood-fired fish and meats, fresh seafood, signature salads and plant-based plates. Proteins are cooked on an open grill, with side dishes forming the flair of the meal, all inspired by flavours from around the world. In addition to the main restaurant, there is a beautiful Tea Lounge which challenges the perception of a traditional London afternoon tea and offers a unique experience to all guests. The comfortable Terrace is an elegant spot open for al fresco dining and drinking all year round.

They struggled with the service tonight. Potentially down to a lot of steaks being ordered at the same time or because of a large Christmas booking. However, the staff weren’t particularly attentive anyway.

I thought it was pricey for the food they served.

Lovely welcome - imaginative cocktails.
We were impressed by the wide selection on the menu.
Very surprised that there was no Amuse Bouche - for such a prestigious kitchen.
Steak tartare and scallops were favourites on our table for the starters but I wasn't sure that the large beef-dripping lardons were needed.
Steaks were cooked to perfection but the star meal was the Short Rib - divine!
Wine selection - it was tough to find a reasonably priced wine!!
Service was superb - attentive, charming and functional

Of all of JA’s places London this is the first disappointment.

Prices are sky high driven by the location rather than by any notable finesse in the kitchen. Service tried hard but was inexperienced..... and committed the sin of the supplying a second £4.50 bottle of water without asking.

That’s rude. Like the bill.

It feels like restaurants of the J. Atherton group are sliding further into “commercial” territory, aimed at maximizing profit and capitalising on the brand. Portions were small, and the menu was uninspiring. A couple of dishes (the fried onion starter) were clearly aimed at the Instagram crowd to create buzz, building expectations which are unfortunately not met with substance. Initial impressions were confirmed when paying the £160 bill for one shared starter, two main courses with sides, a glass of wine, a beer and a cocktail.

First visit here as we were staying in the hotel overnight. Food and service excellent as always. We were seated in lower dining room area which is not as nice as upper dining room and very difficult to get reasonably priced wine though what we had was wonderful. Breakfast also lovely here.

Everything about our a la carte lunch was superb. My reason for giving Value: 4 stars was purely because there was a limited choice of wines under £40 but this wouldn’t stop all 4 of us returning very soon.

Delicious food, excellent service and very well priced. The little extras make all the difference. Will be coming again soon.

Food was great and waiters friendly. Very expensive wine though and not many mid range options

The best meals you can have are the ones that take you by surprise and exceed expectations - this was my experience of the The Betterment. A real pleasure!

This almost perfect meal was unfortunately spoilt by an oblivious waiter. Do not get me wrong, the rest of the staff were fabulous. My starter was inedible, yet no questions were asked as to why I had not touched it. When he came to ask if we wanted to keep our bread, I said ‘ yes, as I could not eat my starter’ this was once again ignored!
As I said the rest of the staff were amazing as were All other courses. We will definitely be back. I must also say Dan the Sommelier is outstanding.

Could not work out if this was a fine dining restaurant or casual dining. Food not up to Athertons Social restaurant standard and wine list expensive for a casual restaurant. Service not bad but could be more attentive. Only 6 out of 10

I'm running out of superlatives ... another dinner here with different friends. Warmest of personal welcomes, lovely to see a couple of changes to the set menu so I was able to have something different. Crab on toast was Divine with a capital D; the pork was gorgeous again and the new chocolate mousse dessert is a keeper! Lovely bottle of NZ red and a special gift from Orlando (scrummy onion star/petal). It won't be long before I'm back ...
