The site is setup as any other store would be for products of all types.

Top Level categories = Restuarant name. Subcategories under each restaurant name holds the menu categories and products in those categories are listed under those. You can see and example of what I have set up so far on the site at this url: www.angletonexpress.com

I still have tons of work to do to the site before it is ready to go and currently have it set to be a showcase until I figure out how to modify it to work as I want it too.
