In Guui-dong, Seoul, a noodle shop serves kalguksu, sujebi, and kongguksu. The noodles are made by hand rather than by machine, boiled to order, and served in a light broth with sweet kimchi on the side. The shop opens at 11 a.m., and food takes a while to arrive after ordering. At lunchtime, the wait outside can run 10 to 15 minutes.
