The first lounge I visited was in T1 as a teenager. I remember it feeling quite magical as I'd never been in a lounge: Welsh dressers full of treats, parasols and sun loungers by the windows overlooking the apron/north runway, and (if memory serves correctly) a fountain. It was also the first time I drank black coffee and I've never looked back!
The tiny GLA lounge was homely but the new one is miles better!
