Completely agree with the superior quality of the concourse A lounge. However, I must say that I haven't consistently found "a much better selection of wines" there versus B or C; special bottles appear and disappear in any of the concourses, without any particular logic. I would say it's random. Cuban cigars used to be available for purchase (at relatively decent prices) in the smoking lounges. They disappeared a few years ago. So, onenation1994a if you want to have a smoke bring your own (the selection at DXB duty free has also been poor lately, and prices keep being adjusted upwards, to the point that it's no longer worth buying there).
