Using archive pages as pillar pages and in menus

Hi,

I am building a directory site and want a menu that links to my main category pages. The category for the products is also what I use for the faceted search and breadcrumbs.

As an example, I have created a page for restaurants that lists all the restaurants and is linked to the main menu. I have also turned on breadcrumb and this has created a category page that is similar in that it lists all the restaurants on the site.

Would it be best to delete the original page and just link to the category page created by the breadcrumbs in the menu? or would there be a negative impact doing so?

any advice would be greatly appreciated!

Thanks,

nick
