Geumgangsan Sikdang is a tteokbokki restaurant in Cheonan. It serves don dok tteokbokki and whole-squid seafood tteokbokki with udon noodles, tonkatsu, hot dogs, or squid added, along with shrimp basil cream pasta. The tteokbokki portions are large enough that two people leave some behind. Seating is closely spaced and the tables are small, which makes eating uncomfortable.
