Our Inspector's View

The Betterment is the Mayfair branch of Jason Atherton’s London operations, occupying a glamorous setting in the ultra-luxurious Biltmore Hotel in Grosvenor Square, so this is not one for tight budgets. It’s the sort of glitzy spot for putting your glad rags on in anticipation of some big-hitting dishes that tease out every molecule of flavour from pedigree ingredients. Roasted Orkney scallop with braised girolles and creamy Parmesan sauce opens in fine style, while short rib with Montgomery cheddar and bone marrow is lifted by the textures of croutons and diced apple. Almond financier with caramelised white chocolate, raspberry and red pepper sorbet makes a refined finisher.

About The area

Discover London

The UK's capital was founded by the Romans shortly after they invaded in 43AD. Since then it’s evolved into one of the greatest cities on earth. From a bloody, squalid history to the vanguard of fashion in the Swinging 1960s to the buzzing metropolis it is today, London has something for everyone. There are very British pursuits like the Oxford and Cambridge boat race, changing of the guard at Buckingham Palace and an impressive collection of traditional English pubs. And that’s not to mention world-renowned arts venues, galleries and museums, award-winning theatre and unrivalled shopping – all found within a few Tube stops of each other.

London’s royal history is not to be missed. Visitors can roam around one of Britain’s finest medieval castles and royal prison, and learn about the final days of Anne Boleyn at the Tower of London or, for the less bloodthirsty, visit the Queen’s London home, Buckingham Palace. Don’t miss out on exploring the capital’s Royal Parks – from St James’ Park and Hyde Park in the centre to the majestic Hampton Court and wilderness of Richmond Park in the southwest.
