I'm assuming this applies to Norwegian, and not Avoya.
This was the second cruise with Norwegian, and hopefully won't be our last. I love the free-style dining and more casual atmosphere; although my wife would differ with me, preferring a little more formal atmosphere, at least for a couple of the dinners.
I liked the service, although I will say that some of the service in the dining rooms was a little slower than what we've grown to expect on our cruises. And the portions, while ample, were noticeably smaller. But there was still plenty to eat!!
