Hello Michael, welcome to WebmasterWorld!
Here is a breif summary of what I believe is a good strategy:
Make your hallway page into a "site map" type of page. Each link to a page should include a description (keyword rich, of course) of what you will find on that page. It is also a great idea to arrange the page in a directory fashion. For example
-this site is designed to bring you the best information about cool widgets. Yadda Yadda...
-we have a large selection of cool-blue widgets. Whether you are looking for light blue or dark blue widgets, we can help you find what you are looking for.
-check out our new cool-light-blue-widgets. These are great for widgeting on special occasions. We have sizes S-XL.
Basically it becomes a directory page with real value to your customers/users. They should be able to quickly and easily navigate the page.
And....you get a page that spiders will (hopefully) spend lots of time jumping from.
