Noooooo!

The QR F lounge is by far the best for food of all three (QR, QF, BA), and usually very quiet. Nice showers too. If you don't have QR access (not travelling J or F, or it's not open yet) then QF F is good for food but the BA showers are better than QF in my book.

Although the staff in the BA F area couldn't be nicer or more helpful, the food is just someone going round the J buffet for you and it's not the most convivial spot. We tend to go there for 30 mins before boarding because it's peaceful, but it's genuinely not a great place to spend time in comparison to the other lounges.
