I am looking for a venue preferably that's free, to hold an all day workshop for about 20/30 people. I would need coffee/tea and soft drinks for the day. Some candidates may buy lunch time food from the venue if its served. I would need a room with table and chairs but also some clear space for meditation. I would also need a power socket. If anyone knows of a suitable venue your recommendations will be greatly appreciated. Many thanks PKTS
