At 93, Boman Kohinoor, the owner of Mumbai's iconic Britannia restaurant started during the British reign, may just be the oldest, loyalist, and biggest fan of the British Royal Family. In a video shared on Facebook, Me Kohinoor explains that he had written to the Queen in 2010, inviting her to visit him in India. She wrote back to thank him, on a letterhead stamped with the Windsor crest.
