We had an excellent couple of hours in the gold lounge North a few weeks ago, as we couldn’t access the AM lounge, due to being in QR business, but in the lowest fare class.
Mid afternoon, it was empty, I had a lovely shower, Lanson black label available on tap (or any other drinks) from the manned bar. Food offering was quite minimal, but I didn’t need much between Qatar J flights. No issue guesting my ba Bronze partner in, as a BA silver and good airport views during daytime hours.
