Instagram photos from real-life passengers show an array of sweet treats likely to be popular with Prince George, Princess Charlotte and Prince Louis. While one photo reveals decadent pastries filled with pistachio and drizzled in honey, other pictures show chocolate fondue served with marshmallows, shortbread and fresh strawberries.

The royals can order as much as they like from the VIP menu

More posts from the Terminal 5 secret spot feature decadent dishes fit for the King, including BBQ pulled chicken with celeriac slaw, spiced sea bream with warm chickpea and samphire salad, confit tomatoes, charred aubergine puree and saffron aioli and steamed seabass with bergamot marmalade and pickled fennel.

Priya Malhotra, head of Heathrow VIP, previously told Business Insider: "You can order from the menu as much as you want.

A pass to the Windsor Suite gives guests access to unlimited Champagne

Kate and William's culinary luxury doesn't stop when they leave the lounge, as British Airways fine dining menu for first-class passengers is a feast for the eyes.

Previous seasonal menus have included oak-smoked Gressingham duck, Italian burrata with summer truffle and lobster tortelloni with clam and sweetcorn chowder.

At over £3,000 for a two-hour service, dining at the royal-approved Windsor Suite is a steep affair, though not off-limits to the general public. Anyone willing to splash the cash for this luxury VIP service is welcome to - you just have to be a first or business class passenger! We'll stick to the Pret sandwich for now...
