What is the name of this delicious Korean hot pot?

I had this Korean hot pot at a restaurant several times now but I keep forgetting the name. It’s a red seafood soup, with thick white noodles, tofu, watercrest, Chinese cabbage, and every kind of seafood possible (lobster, clams, shrimp, eel, fish, scallops, etc.). What is the name of this hot pot? And can anyone give me a recipe for the broth?
