My parents just flew LHR-EWR and YYZ-LHR in CW.
They're not frequent CW users but remarked on excellent food outbound to EWR.
They said food on the return from YYZ was 'awful' and from their description of the menu it sounds like it is still the 'old' food. They did however get the new bedding.
They remarked that they feel the new amenity kit is a downgrade which was was surprised about. Maybe because my Mum loves shoe bags.
