Before stopping by for the first time yesterday, I saw several times Cafe Heider in Potsdam, but never entered it. It is situated in the area with shops and nice restaurants and other tourist attractions, and when the time is mild you can even stay outside to watch the people coming and going.
It was founded at the end of the 19th century, in the classical style of Vienna, as a big open space where people are not only having their early or late breakfast, but where they also can know new people and find out what is going on around the world. This role was maintained till today, even though the entire location was refurbished at least once.
I arrived there around 9 in the morning and when I left, two hours later, the waiters had a lot of work to do. For those interested in a nice business discussion, the upper floor is the perfect location of a private setting. If you plan a bigger networking event, it suits such an opportunity as well, because there will not be outside bothering and there it is enough place to host around 20 persons without problems.
The prices are above the average. If you want to have your breakfast there, be sure that you have in your pocket at least 7-8 Euro. You can have an 'apfelstrudel', or a fruit salad or if you are so hungry and no diet pressures, even a schnitzel.
