Additional directory listings

Hello
I am building a directory of breweries in my area. My hope is that there is some way to include a “sub directory” into my listings. For example you end up on the detail page for a local micro brewer names Joe’s Brewing. All of the detail page information is there but at the bottom there are a few “mini profiles” of bars that sell their beer. This could be a sidebar as well. the hope is that you end up on the Joes Brewing detail page and then you see the places that they recommend you go buy their beer. Not sure how to do it but it would be cool.
