This is a famous ramen restaurant all over the world. The first store is located in Japan. Their ramen soak in a strong flavor soup which brew with pork bone for long hours. You can order different flavor as you want. There are spicy miso, soy sauce and so on. Add an extra noodle is not expensive, but worth it. Also the appetizers here are delicous and tasty.
The tofu and bun are the two that I recommanded. After you finish the food, you can have the green tea crepe which is from Lady M, one of the best dessert store in Manhatton. This store is 100% Japanese style and flavor. If you are a Japanese food lover, should not miss it.
Booking in advanced is a good choice to avoid waiting there.
