As per our Himachal based sources, Amitabh Bachchan and Diya Mirza are due to arrive in Shimla later this week. In fact, Shimla's historic Hotel Willow Banks (originally owned by Arthur James Cradook- 'Architect and Builder of Shimla')has already been spruced up to welcome the megastar. An old heritage building near the hotel has been converted into a bakery and the necessary renovations were completed on Saturday itself. Why a bakery, one may ask? It is because Amitabh essays the role of a senior local resident who works at a bakery. As per reports, Diya Mirza plays a tourist, who is on a vacation to the hill station, along with a group of friends and is to be a regular visitor at the bakery. Incidentally, Amitabh Bachchan's last visit to Shimla was four years back for Sanjay Leela Bhansali's Black, and on that occasion he had stayed at Woodville Palace Hotel.
