Open philosophical discussion, thinking together about a topic in a philosophical way. The topic will be chosen by the participants at the beginning of the event. No application, no entrance fee. (But as we are meeting in a normal coffee shop, you have to order at least a cup of coffee or tea.) Experience the joy of real dialogue with other people about the really important topics of life! Follow the white rabbit into the wonderland of philosophy... You find informations about me and the event [here](https://sophonautik.ch/english/).

Some people go to pubs. Some people conquer galaxies, build empires, trade spices, or outsmart dragons. Nerdy Fridays are our open board game nights for anyone who prefers strategy over small talk and dice over disco lights. Come solo or bring your crew.

Entry fee: 50 CZK if you drink something, 100 CZK if not (includes access to games and rule explanation) Friday nights don’t have to be loud. They can be legendary. 🎲✨
