Huoguo Nara Gangnam is a hot pot restaurant near Gangnam Station that offers unlimited refills of meat, seafood, and noodles. Diners choose vegetables and meat and cook them in broth bases such as hongtang and mushroom broth, mixing their own dipping sauces on the side. Ingredients are taken from a self-serve bar as desired, and the spice level can be chosen in three stages. The Sichuan-style hongtang has a strong numbing heat, so those who cannot eat spicy food need to select a level.
