Gwanakgwan is a third-generation naengmyeon restaurant across from Anyang Indoor Gymnasium in Anyang, serving Pyeongyang naengmyeon, bulgogi, and mandu. The owner makes the noodles in-house from buckwheat and serves them in a traditional broth, alongside bibim naengmyeon and handmade mandu. There is a large parking lot behind the restaurant, and the seating is divided by partitions. The broth is on the mild side and the noodles are firm.
