I used the first lounge last week before qf94. Crowded, noisy (people on phones and a few babies), and wifi that took minutes to even get an IP address. The food was ok, but I'm not overly fussy.
This is made worse by TBIT airside being the worst and most boring terminal on the planet (Unless I missed the excitement somewhere). Priority boarding was more like a rugby scrum thanks to them paging in the lounge long before boarding even started thus resulting in ~100 people who all thought they were more important than everyone else around the priority area.
