A problem with Yelp's rating system is that it's aggregation of all the user's rating regardless of their ethnicity or background. It means that the rating is skewed towards the most populated ethnicity in U.S.

I'd like to sort the search result for ratings of restaurant based on who rated it. Since I'm Japanese, I'd like to see what other Japanese people recommend especiallu when it comes to finding authentic Japanese restaurant. Because our tastes are closer, I can trust their review more.

I think a lot of people go to pet stores, grooming services, vets, etc. and I think there should be a yelp badge for it. It shows that you love your pets like your own family.
