What website(s) can I go to in order to learn about different types of cuisine? (Italian, French, Greek, etc.)?

Question:

I want to purchase the Gordon Ramsay World Kitchen cookbook, but I want to know more about them first.

Answer:

I would go to YouTube to look at different recipes.

Also, about.com has different cuisines.
For example, for French food, http://frenchfood.about.com/
There's one for Italian, Japanese, Chinese... etc.
