Looking for Business Directory with review system

I would like the ability to add a business directory to my website (or even a product directory, if I could add businesses instead!). So far none of the ones I’ve found look functional.

Ideally it would be like yelp, where people can add comments. I would prefer for it not to be a blog post system, as I already have a blog on the site. I also don’t want users to be able to comment/rate my other posts.
