A 50th birthday usually calls for a huge celebration, but superstar Shah Rukh Khan, who will touch the half century mark on November 2, says he has plans for a ‘quiet’ special day with his family. “I will have a quiet birthday. I will go back to Mumbai on November 1 to meet my children, because the next day I have to be in Goa for a shooting,” said the actor, who has been shooting the last leg of Dilwale here for a month.
