My wife likes Trader Joes a lot, which is fine with me. She will claim the apples there are better than Krogers. In my experience, they are all the same, highly variable, some good, some not, same with Whole Foods ($$$). At times, I've noted to her than the apples I got at Kroger are quite good, if they are, and those she got at TJs are mediocre, but it doesn't seem to alter her opinion. I really think the apples all come on the same truck so to speak.
I thought the pineapple on the ship was really good, but she claimed they were too sour. Ok then. The watermelon was good at times, and had little flavor at other times, same with cantelope. I presume they restock at various ports. They told me all their meat came frozen. That surprised me. The steaks were pretty good. I usually get a sense when meat has been frozen.
We had an interesting tour of the innards of the ship, including the kitchen and a chat with their top chef. It's pretty amazing, to me, the operations are ... not simple.
