In Short: Better than average food, but awful service. Try the stew, pretty damn tasty.
Used to be the best Korean place in town but there have been a steady decline in the last few years. Quality is a little down but the service seems to have taken a cliff dive without a parachute. Takamatsu is probably the best Korean in town these days.
The korean stews in the stone bowls are so amazing, I pretty much go here for that and the bulgogi. This may not look very appetizing but try the pork salad, it's a behemoth collection of greens topped with pickled pig feed sliced thinly, very tasty. The accompanying small dishes are pretty delicious too, but they used to give better quality stuff like real fish, and tofu cakes. I still go here occasionally for the food but I wish they get a clue about customer service.
