Kawran Bazaar, which really comes to life after midnight, is the entry point for much of the food in the Bangladeshi capital. According to a recent World Bank study, Bangladesh is among at least 33 countries that are at risk of serious political unrest if food and fuel prices keep rising. Bangladesh is currently one of the world's poorest countries, where nearly 40 percent of the 144 million population survive on less than a dollar a day and on average spend 80 percent of their income on food.
