Firstly: restaurants need to be divided into categories and ranked within the category.
5 star McDonald’s is worse food than 1 star fine dining. (Regardless of number of visitors.)
In the fast food burger category that Mickey D might be the beating a 3 star Burger King hands down in cleanliness, friendly customer service and timely orders.
Secondly: You need to filter out the average Joe’s.
Especially with regards to ethnic food, they try an amazing Pho and be like ”meh, too bland - the mexican one was better”. They’re two different kitchens! You can’t compare them.
