On our Constellation cruise last February, the MDR food was still the best MDR food we have had on a cruise ship. That said we have only sailed DCL and RCCL.
One or two critical posts, I would think it is picky eaters, but with as many as there have been I wonder if the food quality purchased is down or if they are trying to do less due to increasing food costs. Seeing 18 eggs for over 8$ at our lowest cost grocery store in the area opened my eyes, I only shop Costco usually and I know meat prices, etc are up. I can't even imagine what this does to the costs the cruise lines are paying.
The above isn't an excuse, but could be part of the reason. To the OP I am guessing we are part of the same FB group and I wouldn't dare post the above on there lol. I am not an apologist yet, but we do have 3 Celebrity cruises booked so I am on that path.
