Unlike what most think, it is more than a simple pizza joint down the road. It is the term used to describe being high to the point of absolute peace in the mind. You achieve the highest state of mellow. It is named this because the drug often used to achieve this state of mellow is the shroom.
Bob Marley founded and represented the Mellow Mushroom society!
