The Takadanobaba and Waseda areas in Tokyo are known for a large number of ramen shops and their rivalry. Ramen Yamaguchi is currently one of the most popular shops in the area. Their broth is made with highly-priced free-range chickens in a soy-based sauce and has a delicious flavor and a mellow fragrance. People eating here for the first time may be surprised by the very robust dish in contrast to its simple appearance. The shop is often busy in the afternoons but is ramen worth waiting for.
