A new food delivery service called FlyingFoods has been launched in all the major cities in South Africa. FlyingFoods charges R15.00 for delivery, but it states that it will deliver to your location within 40 minutes of placing your order. FlyingFoods have received great reviews for Bloemfontein and Polokwane, but very poor reviews for Johannesburg and Cape Town. The reviews for Johannesburg and Cape Town indicated that the food took much longer to deliver than expected, and it was therefore also cold by the time it arrived.
