I scrape all of the food, wine and beer recommendations that I find and display them on a map in a web app. I can see the list of all of the places that are closest to me: restaurants, wineries, ice cream parlors, breweries and so on. If the source of the recommendation scores places or products made by it it's part of the data and I can filter by the score. I probably spent many weeks working in it. I'd love to make it a business but I have no idea how to approach the legality of it. I use it all the time because I travel a lot.
