Mashitneun Sundubu
This little neighborhood spot is all about the silky Korean soft tofu known as sundubu, served bubbling hot in black earthenware pots. They also have meals for two with tasty extras such as stir-fried spicy pork and octopus. It gets slammed at lunchtime, but the home-cooked style food is an outlier in shiny Centum City, so it's more than worth the wait.
