Hi
I recently achieved Silver status

, and am travelling (with companion) from Heathrow T5 to Berlin on the Friday before Christmas at 7.20pm.
I've not travelled through T5 yet, and am looking forward to it. I'm after a bit of advice on which of the three Galleries lounges is best to use? Are any of them quieter than others? Could I theoretically use any of the three anyway, or am I limited based on my destination? Are any of them better for food, as we'll get something to eat while in the lounge. Or, given it will be a busy Friday early-evening, does any of this matter as they will all be very busy?
I can appreciate this post isn't important in the grand scheme of things. However, all comments are welcome.
PS I guess there are no lounge tips for Berlin, except to use the one lounge available...
