I agree the withdrawal of the cafe would be a loss to people who come to the park and go to the cafe, but how many do.  A mention is made of a petition, but I am surprised there is no indication of a link to the petition, if the article was in support then a link would have been included, as it is The Star have just used it as another news item.
I would also question, what the Kudos Group is proposing to do with the space used by the cafe. I am assuming that the contract was for use of the whole building, if so they will be extending into the cafe area for the core reason they wished the contract for.
The council say they are unable to find an operator to run the cafe, but the council from my own experience are no experts on running or finding people to run businesses.
As they say an operator may be found to provide a kiosk or refreshment service elsewhere in the park.  While this would not have the grandeur of the building, it would still be able to have the peace and tranquillity in beautiful landscaped gardens.  This again assumes that the contract did not include the garden area located with the building.
For a supposed article in support of the use of the cafe, there are a lot of points requiring further information.  Also it is published on line on a Sunday, when there is no official printed publication.  
I wounder if it will be included in the Monday printed paper.  One will wait and see.
