Home delivery in Asia Pacific is notable not only for its size but also for its concentration within fast food. Fast food leaders have made delivery a key part of their local business, using fleets of brightly-coloured delivery scooters that can easily navigate congested city streets. Asia Pacific claims 52% of global fast food delivery, but perhaps not for long. Burger King is testing delivery in North America, and McDonald's has called the potential for US delivery "a big, big opportunity".
