Nihari is a traditional dish of Muslims of Delhi, Bhopal and Lucknow. After the creation of Pakistan in 1947, many Urdu speaking Muslims from northern India migrated to Karachi and other cities in the eastern wing (now in Bangladesh), and established restaurants. In Karachi, Nihari became a roaring success[6] and soon all over Pakistan. Now Nihari is available in Pakistani restaurants around the world. Nihari[7] is considered to be the National Dish of Pakistan
