We just got off the Sky 12/27 after a 10 day cruise. The food in the MDR was delicious, the IC was amazing as always, Alfredos continues to serve the best pizza at sea, and the buffet was fine. I've never left the buffet feeling like I ate the best meal I've ever had so my expectations are low for that venue. I also think that these issues are ship specific. Some are reporting wonderful experiences and other ships' offerings seem to be less stellar.
If you're in the US like me, you may have noticed that the variety and brands of food in the grocery store is not as readily available as it was 2 years ago and the costs have risen. I think the chef is doing a great job with the reduced ingredients available and trying to contain costs. I think those of us who love cruising are going to have to moderate our expectations for a while until the industry is fully back. It's like loving your team through the lean years. They will come back champions soon.
