Thanks @alexjordan_now! Yeah, I've thought of St. Oberholz, not of Mindspace though, thank you. Let me add both to the list of where to try it out.
@sjagarinec thanks for the locations, what scares me of those platforms is always this €50-€100 price range. We're looking for places that we get for free and the drinks are ofr purchase, or even better sponsored.
