Whilst I agree that some of the offerings are pretty poor, compared to BA (just an example as they are the airline I most often fly these days), the food in the QC's are definitely better - BA lounges often push packets of crips and twiglets rather than any real food. That said, I don't think Dixson would need to do much in order to vastly improve the offering.
Looking forward to when they create a WP lounge as at least it might solve some of the capacity issues by separating people off into a new lounge. That's said, I hope they don't make the current QC's any smaller as they really do need all the space that they currently have.
