i think it is a cool idea. i had a similar idea a few years ago, where you could take bar data like beer and food prices, and make an app collect a bunch of data, and then make a recommendation engine using the data. I started to build it and found out quickly that getting that data was a lot harder than i thought (most of the bar menus were pdfs of images, and could not be mined of text). Since then, foursquare has come out with the explore feature, which is very similar, but as far as i can tell, they are no using bar items (food,beer,price) as features for their recommendation engine. Your idea is cool, but I bet it will be a pain in the ass to scale.
