Kanna Grilled Chicken Noodles is a noodle shop near Exit 4 of Gangnam Station in Seoul that serves kalguksu topped with grilled chicken. The kalguksu uses house-made noodles in a well-simmered chicken broth, with two whole grilled chicken legs placed on top. A bowl of rice comes at no charge. Seats by the entrance are cold because of customers passing in and out.
