When Amit Jatia, vice-chairman of Westlife Development (WLDL), which operates fast-food chain McDonald's in West and South India, wanted to become the American fast-food giant's local partner in 1995, he had to first convince his family he would remain a staunch vegetarian. As McDonald's - home of the iconic Big Mac - completes 25 years in India, being one of the largest operators in the quick-service restaurant (QSR) segment in the country with over 300 outlets, Jatia has held on to the promise he made to his family. Not one to sit back and watch anyone flip the Big Mac, he gets straight to the meat of the matter when he says McDonald's success menu will see the QSR expand its ever-hungry 'foodprint' by doubling the number of joints and increasing its average unit volume by 35-40 per cent in five years.
