Tantan Noodles Kitchen Gangnam is a Seoul restaurant that serves ramen centred on tantan noodles. Its basic tantan noodles come in a clean, nutty donsagol broth without a strong peanut flavour. After finishing the noodles, you can mix bokkeum kimchi and a mini bowl of rice into the broth, and the rice is served only when you ask for it. Spicy menu items such as Sichuan tantan noodles are quite hot and pungent.
