New Roumen Guanzi is a restaurant in the Namcheon-dong alleys of Busan that serves Taiwanese food, including beef noodle soup and wonton noodles. The beef noodle soup combines a broth of dried flounder and chicken stock with chewy noodles and soft meat, while the liangmian is a Taiwanese cold noodle dish with peanut sauce and cucumber. On a Saturday around 1 p.m., the wait was about 15 minutes, and Taiwanese broadcasts play inside. The beef noodle soup is fairly spicy because of the chili oil and spices.
