Tsukeru is a Japanese ramen restaurant in Seoul that serves tsukemen and mazesoba. It sits on the ground floor of an alley across from Hongmungwan at Hongik University's main gate. The signature tsukemen pairs thick, chewy noodles with a tangy broth based on pork stock and bonito. Orders are placed at a kiosk, noodles come in 200g or 300g portions, and the wait can reach about 20 minutes at peak times.
