It was fun reading this "live from" after the fact, as we were on the same cruise. It was explained to us the snails delivered by the vendor were of poor quality, hence no escargot. Same with arugula. My beef carpaccio came smothered in field greens!
We also experienced the jam shortage, although I found one jar of cherry on disembarkation morning.
I mentioned on another thread our we had to refire three bowls of mussels and two lobster bisques on night one over temperature issues. My wife was quite acutely ill the next morning. While we could certainly not prove a causation, the Sr. Exec Chef and Restaurant Mgr insisted on meeting with us to discuss it. They were very attentive and offered an extra night at Jacques. Two nights of goat cheese souffle, my single favorite item on the ship. The OP mentioned early on where O outshines =X=, but the wifi is a miserable failure when you compare the two.
=X='s "free" laundry is also far quicker to return.
We were in a PH and found so much storage and the room so well laid out we left more than a half dozen drawers empty. None of that silly brick a brack found in Revolutionized =X= suites.
Just my two cents. Enjoy your cruises, future Riviera travelers.
