Technology company SAP has a base almost in Hackesche Höfe. Part of it is the Data Kitchen, a pretty cool proof-of-concept for a next-generation lunch restaurant.
With an app you can order your food and drinks for a specific time, and pay as well. Once the food is ready, you can unlock a cool box with the app and enjoy your Sauerkraut in a restaurant-like atmosphere. The daily special is good value-for-money. It ain’t super cheap, but quality is unusually high and it is at the least a good experience.
