Great experience departing BER last week. Fast track security <5 mins, Templehof lounge was quiet with a solid selection of drinks (including beer tap), local breads, sweets, plus a couple of unremarkable hot food options. Really enjoyed the private passport control lane (no queue) which can be accessed direct from lounge. If I was to be picky it was too hot on one side of the room (possibly AC not working), but thumbs up from me overall.
