I really love this concept! They have a pretty comprehensive directory of restaurants in NYC. Sometimes the address is incorrect, but if you report it, they fix it in about 24 hours.
I have two suggestions to improve it. Number one would be to rank restaurants ONLY amongst other restaurants in their category (either by Cusine category or based on the tag (date night, brunch, cocktails, etc.)) Otherwise, what happens is you start comparing apples and oranges. It's not fair to rank a Korean BBQ restaurant against a brunch pancake spot or against a lunch deli. There isn't a comparison there. My rankings can get a little wonky and overstated or understated because it makes me compare restaurants to other restaurants that are completely different aesthetics or purposes. A fancy dinner date spot isn't comparable to a bagel shop. It would be great if I could either rank all of brunch spots against only brunch spots. Similarly, all of my Italian restaurants against ony other Italian restaurants.
Second is to add more tags. They're kind of random right now! A good few to add would be: brunch, first date, healthy, aesthetic interior, rooftop, etc.)
