Share interesting stories you found from the data

The highest rated ramen was the ramen bar. It had 5 stars, no other type of ramen had 5 stars. The highest rated ramen out of any other counrty. This makes sense because ramen was invented in Japan in the 1860s. I think this is very interesting because I have never had authentic ramen but my great uncle lived in Japan for many years teaching children spanish and always talks about the cuisine. I also think its interesting that the United States is in the top three nations while the other two are South Korea and Japan. It shows that the United States is only there for the sake of production.
