3.5 stars for me. Solid late night option when you want to get your Korean food fix. My favourite dish to order here is the kamjatang (pork bone soup). They give you a good portion of pork along with potatoes and kimchi and a bowl of white rice. They also give you a variety of banchan (side dishes) such as kimchi, radish, spicy cucumber and bean sprouts. You may also ask for more side dishes at no extra cost.
There are a wide variety of dishes to choose from here such as kalbi, bulgogi and green onion pancakes. I recently ordered a combo consisting of spicy bulgogi, rice and a fried egg, solid but not spectacular. For a place open 24/7 you could certainly do a lot worse.
