Since Samcheok is a coastal town, it's known for its hwae and gul (oysters). There are several places to get good seafood in the area. At Haedoji Hwaetjib, 1-beonji, Jeongha-dong, Samcheok-si (tel. 033/574-1575 or 574-7785), you can get your fill of fresh fish, from W10,000 for ice hwae to up to W100,000 for a huge platter to share with your friends. Open daily 10am to 10pm, it's located on the bottom floor of the Viking building (look for white Korean letters on a dark blue background).
Another nice place to enjoy the local raw fish is Bada Hwae, 41 Jeongha-dong, Samcheon-si (tel. 033/574-3543), which has mixed fish platters you can share from W30,000 to W50,000. They're open daily 7:30am to 10pm, except holidays and every second Monday.
For oysters, try the Gwaneum Gul Shikdang (whose name means "oyster restaurant"), 2-bang, Daei-li, Singi-myeon, Samcheok-si (tel. 033/541-1624). They have spicy seafood hot pots for W20,000 and even a roasted chicken meal for W30,000.
For a more economical oyster meal, head over to Gulpajib, 203 Daei-li, Shingi-meon, Samcheok-si, where oyster flatcakes, mixed rice bowls, and potato flatcakes will cost you only W3,000 to W5,000.
If you're hungry for a big Korean meal, head over to Sae-eunhae, 1-6 Seungnae-dong, Samcheok-si (tel. 033/573-7969), which is located right in front of the Samcheok Medical Center. Open daily from 10am to 10pm, the place is popular with Japanese tourists. The best deal is the yonsama (which means Japanese royalty) meal for W10,000, which includes a generous variety of banchan (side dishes). If you're not that hungry but want to cool off in the summer, you can get a bowl of naengmyeon for only W5,000.
Also, the road up to Hwanseon Cave is lined with casual restaurants, all of which have fresh local offerings with comparable prices.
