BMI card will get you in. I did not use the BMI lounge, did not have enough time when running through the place recently. In the *A lounge, space was restricted from when it was the BA lounge in T1, and the space felt a bit more claustrophobic - low lights, lower ceilings than used to be the case (or so it felt), and smaller footprint. I did not thoroughly explore whether there is more space that will be added, or a First class lounge, or anything. It really was a run-through.
They had a couple of self-service food stations with hot and cold offerings. Usual breakfast stuff with a couple of bacon sandwich type things, which I did not try; it was about coming up lunchtime, and they started bringing out several indian hot appetizer things, samosas, pakora stuff, which was very tasty. A bit spicy even, some of it, which is very welcome, and a bit unusual. There were soup and stew offerings, which I did not try. Felt like a very very reduced scale offering of the sort of thing that gets put out in Galleries in T5 now. Better than what you got in the old BA I thought.
Drinks selection is limited - as in don't expect a choice of three different gin and vodka brands. But all the basics are there to fix a drink. No sparkling wine was visible, and I did not have time to enquire as to any being available, but did not see staff milling around with bottles either.
Hope this helps.
