It’s a battle among the top three food apps: UberEats, Skip The Dishes, and Foodora. We test these delivery giants for speed, cost, presentation, and hidden mark-ups. It’s big business, about $2.5 billion worth and growing. The technology is easy to use and foodies can order from endless local restaurants. So, what’s not to devour? Deliveries are late. Meals arrive cold and others ruffled up in transport. Dishes are missing and sometimes the entire order doesn’t show up. On top of all that, many of us aren't aware of the actual costs. There are hidden fees that even savvy users miss. So who’s responsible? Is it the couriers, the mobile apps, the restaurants or our desire for convenience and instant gratification?
