Is that the Malev lounge in the Sky Court Terminal? Priority Pass are (still?) showing this. They are usually quite good in updating details.

They also show Platinum Lounges in T2A and T2B and the Millennium Lounge in T2B, but the T2B lounges are closed for refurbishment until approx 15 Feb 2012.

ETA: the Platinum lounge in T2B is near Gate 18, though currently closed. If this is the same lounge that BA used, it would seem that qualifying BA passengers could still use it.
