Had the same decision to make and hadn't been to either so this is my thought process:
1) Knew we would like atmosphere and characters, but would we like the Norwegian fare at lunch & dinner. Nothing on the menu really called out to me so decided on Breakfast to be safe and then enjoy a dinner at one of the others.....Coral Reef that night. Depends on what you want to try food wise.
2) Both wait on you so that comparison was out. Did I want the antics of the staff and a louder atmosphere or the spinning of the restaurant and quiet. I decided that I would go for the quiet. At my TS meals I prefer to be left alone. Just depends on what you would enjoy there. As good as WCC food sounded............I went with more relaxing.
