From the streets that surround it, to the feeling that envelops you on arrival - as doormen in top hats and white gloves fanfare you in - this is sheer, shameless luxury. Tom Ford and Hollywood celebs are regulars, but all guests are treated like royalty here.
For an all-out ballroom do for hundreds, book the sumptuous Mayfair room (below). The hotel is extra-welcoming - expect pageboys and flower girls to be spoilt.
