As well as cocktail making and getting to go behind the scenes at Gordon Ramsay's restaurant Maze, you can try a make-up masterclass and discover how to get the ultimate hotel luxury and style in your own home.

And if you've always wondered what life in a hotel is like from the staff's point of view, head concierge Harry Miles, who's been working there for 25 years, is also taking part in an afternoon tea event to tell the history of the hotel.

Since it opened, the hotel has been home to a string of A-listers and even royalty, as well as innumerable guests. Built as a stately townhouse, it's undergone a multi-million pound refurbishment to become an urban retreat it the heart of Mayfair, just a few minutes from Oxford Street and Bond Street.

Quick facts: The events are open to hotel guests and non-residents – see the schedule for October at and for more information on booking. Every event is free to attend for up to 25 people.

The hotel is also running a 25% off deal if you book for three nights, with rates starting at £149 per night.
