This was literally the rationale behind the relaunch of reviews in Google Maps in 2010-11, and what you describe was exactly the internal demo that got the project staffed and funded. I'm not sure how much of it still exists, but for a while, when searching on maps, there were little tags on recommended places that said something like "recommended because people like you also liked X".

That project never really reached its full potential for other reasons, but it turns out that even with a lot of data, it's hard to make big gains in ranking over just using the aggregate of all users. The intersection of two people's tastes is sort of surprisingly not very helpful.
