Fondly known as the "volcano ramen", the signature Kazan ramen is served in a hot stone bowl, and is covered with a conical red lid after the soup is poured in, causing an eruption of steam. If you're still hungry after finishing the noodles, add the bowl of rice into the still hot soup. The noodles are broad and flat, as they believe it does not turn soggy as fast as thinner noodles. Go for the Kazen Kaisen-shio, a tonkotsu broth full of seafood.
