Most diverse food
 

Which cruise line has the most different offeries for food, I like variety

I'd suggest you look at http://www.cruisecritic.com/, which is the Flyertalk of that particular industry.

Here's an example of information found there: http://www.cruisecritic.com/articles.cfm?ID=1169

Pretty much all cruise lines have a wide selection and variety of food. I know that the "Big 3" cruise lines (Carnival Corp, Royal Caribbean, NCL) offer pretty much everything from Italian to French to Latin American/Mexican to Asian. Most modern ships nowadays have alternative specialty restaurants that are dedicated to a specific type of cuisine. Almost all have an Italian place, a steakhouse, and an Asian place. Even the ship's buffet offers a wide variety of international cuisines for breakfast, lunch, & dinner. Rest assured, anyone with an insatiable appetite will be satisfied!
