The market for food - delivery services accounts for 1 % of the world food market , and 4 % of food sold through restaurants and fast - food chains , according to research by McKinsey . It has already matured in most markets , with annualised growth estimated at 10 % over the next five years . The traditional model of delivery , where orders are placed with individual outlets , accounts for 90 % of the market , and nearly three quarters of orders are placed by phone . Consolidation is advanced in most markets and will likely continue. However , these models are being challenged by digital incomers such as Deliveroo and Google .
