Am very much in agreement with AnaTravel’s perspective here.
Specifically re catering : am conscious that Al Safwa food is not regarded as exceptional, though nor do I recognise the very poor quality as described by relaxonbarton. But in fairness, each to his own and you can only speak as you find.
All said & done, airport lounges - even the most luxurious - do not present themselves as high-end restaurants and they are, in essence, ultimately intended as waiting rooms in which to relax (or sometimes work !) ahead of a flight. And by that measure, I consider Al Safwa an excellent facility in terms of comfort, space, calm - and service (if actually needed). If you have ever used a BA First Class lounge at LHR (esp. T5) during a really busy period, or even their CCR, with noisy types shouting into their mobile, then Al Safwa by comparison is a true oasis.
