There were probably only 50 -75 people there. The filmmaker was there too, and took questions after the film was over. He lives in Evanston. The film is also available at Amazon, and if you are a prime member you might be able to see it for free? I am not a member of Prime and so I am not sure. This movie came out in 2017, he just came out with another documentary too that he was promoting, but I forget the name of that film. They got beverages donated by Newport Coffee House which is a new coffee house in Evanston next to Koi, and some restaurant donated the rest of the food, some of which I am sure is not sustainable. They did have plates made out of recycled paper, and some forks that looked like they were green in nature.
