Pungjo Miyeok Seongsu Main Branch is a miyeokguk restaurant directly in front of Seongsu Station Exit 2, serving seaweed soup and seafood dishes. The menu includes abalone and clam miyeokguk, beef miyeokguk, and flounder miyeokguk, along with ojingeo sukhoe and ttak-saeu hoe. Ordering miyeokguk brings a small grilled flounder as a service item, with one fish provided for a two-person meal. The side dishes are milder than the miyeokguk.
