I believe you must approach this as an experience to include the other diners, the ambiance, the smell, sound and lighting which all enhances the enjoyment. The food is of course healthy and interesting. You start with two small glasses of liquid that was explained but I don't remember. This is part of the super-food aspect. Then you select from the short menu your meal. It is a warm and healthy environment but not a place to fill up for a small amount of money.
I'm not sure about the superfood reality but I did enjoy a lunch here and returned for a pot of their excellent tea.
