Geolocation Business Directory

I want to create a site that specializes in recipes and includes a map directory of local businesses that serve that type of food.

For example, I post a recipe for spaghetti, I would like to include a map at the end that shows local (to the reader – I believe geolocation) restaurants that also serve spaghetti. I do not want to monetize this. I would just like the reader to know – based upon their location – other restaurants in their area that serve it. I don’t want to manually input the locations – maybe just use google maps to locate “like” restaurants based upon the category.

Is there a plugin that provides this type of functionality?
