Might be too late - but here's a few more bits'n pieces about the (stunning

) BHX lounge:
- standard contract lounge snacks: various crisps and crackers
- decent selection of spirits and mixers (port, gin, whisky etc.)
- IIRC 3 - 4 varieties of beer plus a cider
- fancy coffee machine
And the hot tip: they also have wine (red and white) but you have to request it at reception. They'll bring a bottle out and leave it there.
The views are decent as well, looking out over a part of the apron to one end of the runway. There's also a TV where you can watch England (hopefully) trounce Trinidad & Tobago if you happen to be there tomorrow afternoon, but no internet.
I've never had a problem getting in with a *G card and Lufthansa economy boarding pass, even with a guest. Enjoy

!
