Seongjin Agu serves monkfish jjim, seafood jjim, and monkfish soup, and sits near Songdo Amusement Park. Monkfish meat and seafood go in more generously than bean sprouts, and the meal ends with bokkeum bap. The dining room is large, with table seating and floor seating separated, and parking space is ample. The restaurant is old, so cleanliness falls short.
