I was there for lunch around 2 p.m. Most items were still available. The range is somewhat smaller than at Kim Mee Ja Buffet. They are quite strong with soups and grain dishes (e.g. barley rice and millet porridge), whereas I was not too happy with their mock meat (bulgogi and meatballs respectively).
Price is 13000 KRW. There is some signage in English for the dishes, but most of the employees do only speak Korean.
Both for atmosphere and quality of food, I would prefer Kim Mee Ja, but if you are in the Seomyeon area, this is still a good option.
Cons: Few English spoken, Atmosphere could be brighter, restricted opening hours
