Mumbai property magnate's privately held K Raheja Corp, is betting on retail. His listed department store chain Shopper's Stop now has 75 stores, bookstore chain Crossword has 93. Raheja also has interests in hotels; the newest, a 600-room Marriott near Mumbai's international airport, is due to open in December. With sons Ravi and Neel, who help him run the company, he's mulling a REIT listing once the regulations are in place.
