Call it the power of social media.

Princess Kate and Prince William took a break from their jam-packed first day in Mumbai, India, on Sunday to meet with 93-year-old resident Boman Kohinoor, aka their self-proclaimed no. 1 fan in India.

Kohinoor, who runs the Britannia & Co. restaurant in Mumbai, is known in India for his love of the royal family – and the royal-themed memorabilia that covers the walls of his restaurant. When he found out that the Duke and Duchess of Cambridge would be visiting India this month, Kohinoor (and Condé Nast Traveller India) launched a social media campaign to arrange a meeting between the super-fan and the royal couple.

“I do not know their itinerary, whatever it may be, but if they have heard about us, and if they would like to visit us, they are most welcome,” Kohinoor said in an interview ahead of the royals’ visit.

And it worked! Thanks to his hashtag, #WillKatMeetMe, the royals heard about Kohinoor’s campaign and arranged to have a private meeting with him right before their star-studded Bollywood dinner on Sunday night.

“The Duke and Duchess heard about the story of a 93-year-old Mumbai local of Britannia & Co. cafe,” Kensington Palace tweeted on Monday. “[Their Royal Highnesses] were touched and invited him to their hotel before last night’s Charity Gala.” Naturally, this resulted in an adorable photo-op, with the royals laughing while chatting with Kohinoor.

Kohinoor is no stranger to interactions with royals – although this might be his first in-person meeting with members of the British royal family. The restauranteur revealed that he had written to Queen Elizabeth II several times and had gotten responses from her ladies-in-waiting (which he laminated and keeps in his restaurant). According to Kohinoor, the Queen even sent him a large photo of herself for her Diamond Jubilee.
