This spicy soup with tofu, an egg you throw in yourself and your choice of meats or veggies is GOOD. It's hearty, with a great flavor. For not much more, you can turn your soup into a combo and get one of the classic Korean BBQ meat dishes, but I find that the soup is a meal in itself. Both options come with the "panchan" side dishes -- kimchi, tiny little dried fish -- as well as a whole fried fish, a raw egg to cook in your soup, a bowl of rice and the rice "tea" they make with your leftover rice. Good deal for under $10.
Pros: Cheap, yummy and open 24 hours
Cons: Sparse service
