I did use the QR Lounge in BKK, Service is excellent. I usually get myself a table in the dining area (in front of the kitchen). Staff is very attentive, food is good. However I believe I overheard they were running out of the Surf & Turf meal.

I personally wouldn't skip the onboard meal, but just don’t expect (aside of the caviar) anything else than a meal you get in business class. I believe if you have a more attentive crew (than what I had on the same flight as you booked) the experience will be as well better. I didn’t had time in Doha to visit Al Safwa Lounge as my connection was very tight (only 55 minutes) and we landed on a remote/bus stand. Crew let business class deplane first and filled the half bus with C class passengers while suddenly realizing First class passengers should have their own bus. Let me know any question as I took the exact same flight as you booked (ex-BKK).
