They give you a big bowl of kimchi and its REALLY GOOD! It goes great with their food. I had nengmyun and it was really tasty. Ask them for a spicy sauce on the side and add them to your noodles!
Seollongtang is a must here, but also order the sooyuk (boiled brisket) and bindaetteok (mung beanpancake) as your apps. Doganitang, with soft beeftendons, is a sleeper hit.
The kimchi, kimchipancake, and seollongtang were all mind blowingly good, and our waiter was great. If you want Korean food, you really need to try here.
