Awesome Ramen, particularly its freshly-made noodles! (They make it right there based on your order). Never had Ramen noodles that are as good. It's just so impressive. Fish-stock, soy-sause based, fairly simple soup that goes well with the noodles. Non-Japanese visitors tend NOT to be a huge fan of fish-stock soup so I'm actually not comfident you'd like this one, so consider this one as my personal recommendation.
My rating: 5.0+ (Awesome!)
