Guests are invited to attend this decadent celebration - held in the beautiful glass roofed Atrium Lounge - which kicks off at 11am on Saturday 19 May.
After tucking into a selection of canapes, diners will enjoy a selection of traditional finger sandwiches, delicate afternoon treats and a range of 'wedding cake' delights while watching the nuptials, which will be screened live.
Sweet treats will include blueberry violette cake, traditional fruit cake with royal icing, mara de boise, Victorian sponge, grand cru chocolate velvet cake, and to top it off, a 24 carat chocolate soft-centred fondant.
The centrepiece of the Atrium Lounge will feature an oversized wedding cake flavoured with lemon elderflower, the same as HRH Prince Harry and Ms. Meghan Markle.
Guests will be able to take a slice away with them in a branded box along with their menu as a memento of the special day.
The afternoon tea is priced at £50 per person, and can be booked here.
