The city of Oakland rents great community facilities that can accommodate any size group. Some of the facilities are located in parks with access to beautiful outdoor spaces. All are relatively low cost and available on an hourly basis (there may be discounts for non-profits). You bring your own audiovisual equipment but they provide tables and chairs. Kitchen facilities are also available for an additional fee. More details located on their site: http://www.oaklandnet.com/parks/facilities/.
