I recently came back from the Carnival Miracle and found some of the food rather bland. It almost seemed like they did not believe in salt and pepper. They did, however, believe in heavy cream sauces flooding the whole dish.
It's been a while for me, but I distinctly remember the desserts on Carnival being quite bland. I was worried about indulging in too many sweets while cruising, but as it turned out, none of them were worth eating.
