"The purpose of Green Drinks is primarily FUN, but the events also enable people to: share new ideas, learn about opportunities to work for change and to make a difference, discuss the state of the world…Green Drinks can be whatever you want it to be. So come have a few drinks and meet like-minded individuals who share your interest in building a sustainable society and planet."
The event is free but it is recommended that you register online. Feel free to bring some friends or go by yourself and meet new ones. Green Drinks encourages people of all ages and "walks of life" to join their discussion group.
Boston Green Drinks has their Happy Hour on the last Tuesday every month.
