Casual-chic venue dishing up unpretentious Malaysian grub. Ajisen Ramen specialises in tonkotsu pork bone broth and wheat flour noodles. The addition of Shigemitsu’s roast garlic and onion flavouring or “the secret recipe,” in the tonkotsu soup is apparently responsible for the chain’s booming international success. The Kumamoto-style broth comes complete with an egg, chashu pork and kikirage mushrooms. Also on the extensive noodle menu are soy, miso and spicy sesame-based broths and the soup-less dry ramen which comes topped with minced pork, chashu and onion oil.
