Sister Kalguksu is a mushroom kalguksu restaurant near Mangwon Market in Seoul that serves its noodles as a shabu-shabu meal. You eat the mushroom kalguksu in a spicy broth and finish with fried rice. The noodles are boiled once in advance so the broth does not turn cloudy, and the finishing fried rice is made without egg when you order it vegan. The noodles are chewy and the sauce container design stands out.
