Kevin Rose did a short-lived app called Oink [1] a few years ago with the idea of ranking individual dishes at each restaurant. I really thought (and still think) there's a huge potential for this concept.
Every day I have some query like "show me all of the places that serve falafel within 15 minutes of me" or "what are all of the shops with sandwiches in my neighborhood?" Running those kinds of queries on the traditional POI sites like Yelp or Google Maps is pretty ineffective.
You preferences aren't the mean or the median, I suspect.

However, just because a Mediterranean place cooks falafel to order and has tahini sauce doesn't mean that they cook the falafel well, that the service is decent, etc.
I'm also personally _more_ interested in the availability of falafel and tahini sauce than the number of stars a restaurant has, but I use the ranking/reviews to determine which place would be the most enjoyable to eat at. 70% of the Mediterranean restaurants near me may offer falafel, the question is which of them will not be a subpar experience. Unfortunately rankings/reviews definitely aren't always correct, hence this conversation, but I definitely think they still have a place.
Personally I weigh a high number of positive, detailed reviews with photos over the number of stars a restaurant has.
The solution is classification instead of ranking.

Conveniently those are all verifiable facts, so there's no need to wrestle with subjectivity.
