There's a card game around the topic that generates conversation points, part picked at random, part picked by the card colour. It's a great opportunity to chat and get to know people based on what you think and feel about interesting and important stuff. If you love diving deep into conversation and find small talk awkward (like I do), you'll love this meetup. As far as I'm concerned we just skip right to the really interesting conversations and questions around life, love, philosophy, science and spirituality and it doesn't matter how much or how little you already know. They're questions anyone brave enough can dive into with their own thoughts and ideas.
After the card game it's a free for all chat wise, but you'll all have gotten to know each other a bit by that point.
It's the best way I've found to meet interesting people. :)
