Raw fish, called 'hwe', is a traditional korean food, especially in the Pusan area. If you see 'sashimi' on a Korean menu, they may just be trying to come up with a term that's more familiar in the U.S., so it's not necessarily Japanese food. I don't think I've ever seen fin fish grilled at the table in Korea, which means it's either not done or it's uncommon. I've seen shrimp, octopus, scallops (on the half shell) and variety of other sea foods grilled up, though. A good place to go is the new one recently reviewed in the NYT, 36-92. The chal dol baeki is excellent.
