What is Wakayama ramen?

Wakayama ramen, also known as 'chuka soba,' is a regional style of ramen from the city of Wakayama. It's known for its rich and flavorful tonkotsu-shoyu broth, which is a blend of pork bone broth and soy sauce. The noodles are typically thin and straight, and the toppings often include chashu, menma, and a slice of narutomaki. One of the unique features of Wakayama ramen is that it's often served with a side of 'haya-zushi,' a type of fermented mackerel sushi.
