They now have a new coffee machine (at the buffet between the computer workstations and the dining area) in the concourse A business class lounge, along with two flavours of Monin bar syrup next to them. I cannot comment on the quality of the new machine, but the one at the other buffet remains unchanged, as well as the three machines in the SEN lounge.
Also, the business class lounge has new glasses (slightly more stylish than the older ones) which are not (yet) available in the SEN lounge.
