Heads up! Your food could be on its way via a rollercoaster. That is, if you're a guest at one restaurant in the northern German town of Harburg, where orders are placed on a touch screen and the food is served in no time.
In Vienna's roller coaster restaurant, food and drinks have to loop the loop and defy gravity. That's because all the dishes are delivered to the tables via roller coaster. Robots mix the drinks.
Vladimir Putin has a special relationship with Hamburg. He visited the city several times when he was still largely unknown internationally, even once causing a stir at the city hall. Now he's back for the G20 summit.
This will be no easy meeting for German Chancellor Merkel. Disagreement on several issues hangs in the air, while the sideline meetings of Trump, Putin and Co. could overshadow the summit itself, Bernd Riegert reports.
Dishes speed to the tables of a roller-coaster restaurant. What's unique here is that not humans but robots send the food and beverages to the guests. They even mix the cocktails!
