FYI, for anyone travelling the lounge in LHR Terminal 2 is doing quite limited food options - cereals and pastries available to order. Considering there were a max of 10 people in the lounge yesterday morning, this seems entirely reasonable to me, but if you're after a feed - you'd be better going elsewhere. All tea, coffee, wine, beer, soft drinks options available.
I've not been an Aer Lingus silver member for a few years, but was flying on a BA ticket with BA silver status so had access - which was a very relaxed way to spend the morning. Lovely staff working in there too.
