How to control category/subcategory display?

I'd like to be able to display catgeories in a taxonomy without showing all the entries in a subcategory.

For example, I have categories on a site I'm working on like:

products
coffee
dark roast
cd's
foo's cd

and I'd like people to be able to click on "products" and see the types of products, with photos and descriptions, and then to click on "coffee" and get a description of the coffee products and a list of types of coffee. is there a way to do this?
