I took a British friend there in Septemeber on a ex-UK Oktoberfest trip to Munich, made a big deal of flying BA so we could go to the T5 WP lounge.
I was so embarrassed. We couldn't even get seats and there was only a single hot food option. I would have taken the pre-covid BA J lounge any day over that. I returned a few weeks later when I left the UK and it was the same, so it wasn't a fluke.
I'm sure the Concorde Room is a lot nicer.
