The App Too Good To Go (TGTG) enables restaurants, bakeries, cafés, hotels and supermarkets to offer their surplus food at a discounted price to self-service customers. Customers order and pay directly via the app and then only need to pick up their portions in the shop within the specified time window. Participation for partners and customers is free of charge. Customers can conveniently select a shop in their environment and filter out what they want to do with the app. The price is at least half the original price and an average of 3€. This way customers can enjoy a great, inexpensive meal and get to know new restaurants and shops in their city. The gastronomic establishment can sell its valuable food instead of having to dispose of it. This enables them to increase their sales and win new customers, while at the same time engaging in a sustainable and socially responsible manner. The meals saved by Too Good To Go save valuable resources. A total of 6,000 tonnes of CO2 have already been saved. The concept of Too Good To Go sensitises society to the problems of food waste and encourages a sustainable lifestyle. A win-win for all!
