Gogungui Achim is a restaurant across from Changgyeonggung Palace next to Seoul National University Hospital, serving Seoul-style hanwoo bulgogi and Korean dishes. The hanwoo bulgogi includes green onion, mushrooms, and glass noodles, and bulnak jeongol and charcoal galbi-sal are also available. It has held the same spot since 1975 and has private rooms and a self-service banchan bar where you can take the side dishes you want. Visitors arriving by car must use the Changgyeonggung or Seoul National University Hospital parking lot, which makes parking inconvenient.
