I had truffle pappardelle there last week. Amazing. It seemed as though they had put at least half a truffle in it (I'm sure that was a mistake).
About 6 years ago, I used to think GF food was better, but now they are way ahead of even the CCR.
I used the Concorde room on the outbound (using up a GUF2). I asked for soup which was the same muck from GF I think. Better champagne in the CCR though.
But, it's fair to say the GF and the CCR are at the end of their life cycle, whereas The Wing is at the start of its life cycle.
