Probadly the best station cafe ive come across is at Hellifield - open most days and great food and worth a call in if only to look around

There is a good one at Crewe, I used it many years ago, Im sure I recognised it being there last year so it might be still there, in section on platforms 1-5.

I was at Victoria today and saw something which might fit this. It was a lounge area which said, "Northern Belle" on it, and "1st Class" was written on it. It looked closed and guess it used to be a first class lounge.
