Usually fixed price all you can eat places are not my cup of tea. But I found this an enjoyable experience primarily due to the variety of food and the grill at the table approach. We got the ultimate ($21pp) and enjoyed the selection of meats and fish as well as a variety of veggie based sides in typical spicy Korean style.
The service is a bit spotty - family run kinda place. They advertise full bar - NOT. a very small selection of liquor (much of which not stocked - no vodka for instance) and no idea how to pour or mix a drink. Be prepared to stick to beer or a glass of cheap wine.
all told, if you out with a group and don't care about the drinking aspect other than to wash down the food, it can be an inexpensive, unusual approach to Korean fare.
