If you go to this site, Roy has listed the last week's menus including included wine selections:
CrystalMenus2023 | Roy's Grand Voyages (wordpress.com)
Lots of previous, pre shut down, menus as well. This should give you an idea of what is served.
As background I am about to leave for Dubai to board Symphony to reach 50+ cruises with Crystal. I have been sailing with them since 1996. It is by far my favorite cruise line. If you enjoy good food, you will be in heaven. Enjoy.
