I cannot vouch for the food as I have only had passable boiled eggs in the CCR. For me its virtues come down to: the short cut door; the terrace; and the Julian Opie prints lining the walls of the corridor to the loos. Otherwise it's just another waiting room, albeit nicely upholstered.
As with most things BA related, the wise birds on here frequently advise not to get one's hopes up. That strikes me as about right.
