Hi Frankie and welcome to V-Flyer
You should experience a very similar service to the one you had in 2009. The clubhouse is still fabulous and the service there is generally impeccable.
Onboard it will be the same suites, some are now looking a little tired, but still functional. The amenity kits have diminished over the last few years. You now get a snooze pack with eyeshades, earplugs, shoe bag, toothbrush with a small tube of Colgate and a pair of socks. You can have a sleep suit if you want - they are on-demand on the way out and automatically offered on the way back on night flights.
I'm not sure when the baskets of goodies disappeared, but if you remembered a crew member going round with a little basket with pens, polos, lip salve etc. then that has gone now. (Buy them yourself before you board).
If you get a good attentive crew then the service will be very good. Sometimes they miss the mark, even in UC, but we all hope this is rare.
The food seems to polarise people on this forum in a Marmite like way. Love it or hate it. I recently had the excellent risotto with prawns starter and salmon main which were both lovely. Even the fillet steak on my return was good (you just have to accept that it is done a bit too much if you like it rare). Its never going to be restaurant quality catering, because the facilities are more campervan than Claridges.
My advice is have another glass of champagne/wine and enjoy.
Have a great flight and tell us all about it in a Trip Report when you return.
Cheers
Martin
