Fast-food chain McDonald's says it is investing 500 million euros ($557 million) to modernize its restaurants in Germany.

The company says 72 "restaurants of the future" will start offering custom-made burgers, children's play areas and even table service on Monday.

Some of the novelties, such as the new "make your Mac" option where customers can pick their own ingredients, are already available in Asia and some North American cities.

McDonald's says most of its 1,472 sites in Germany will be redesigned by the end of 2019.

The company had revenue of 3.08 billion euros in Germany in 2015.

McDonald's is seeing growing competition from gourmet burger restaurants in many German cities.
