Kimssine Simya Sikdang in Sangsu is a Japanese-style izakaya that serves aburasoba and chicken nanban. The aburasoba is mixed first, then mayonnaise and chili oil are added, and rice is mixed into the remaining sauce. It opens at 6 p.m. and stays open until 4 to 5 a.m., with last orders at 3 a.m. The counter surrounds the kitchen and seats parties of three or fewer, so the small space often means a wait.
