Was in T5 GF a couple of times in the last week after a bit of an absence - a relocation, change in personal priorities, and much less flying. A return to Silver possibly awaits.
I noted the re-organisation of the food in particular, and the hot buffet seemed particularly picked over, even on multiple visits.
The "to order" Mac & Cheese filled a hole, but it wasn't of any sort of quality a self-respecting cafe would want to serve. The presentation totally un-imaginative, just a load of overcooked pasta slopped in a bowl.
Sandwiches were decent - I honestly think these have improved since the time whe BS initially took over the contract - and so I agree with c-w-s in this respect.
One of the main things to remember is that T5 is fast approaching it's 10th Birthday.
This is showing in more than one way.
There's the various bits of powered artwork which were trumpeted massively when T5 was opened, such as "All The Time In The World" and "Cloud" which have stopped working some time ago and never been repaired.
On a more functional level, we saw the replacement of carpeting and soft-furnishings in 2015 - remember that these were becoming decidedly worn and tired.
But, things such as the toilets are now definitely showing their age, for instance damaged and chipped finishes, stained toilet bowls, broken coat hooks or shelving, and the back-lit ceilings being full of dust, punctuated by the occasional dead insect.
