Ordered the samgyupsal, and the galbi; The galbi was my favourite - melts in your mouth.
The grill was too hot and it cooked the meat faster than I liked, and oil was kind of burning us in the process, but the service was friendly enough to help us along, even in putting/flipping the meat for us on occasion.
The restaurant is a little dark, and could do with improved ambience, but I think the popularity really comes from the food, and great side dishes.
Would've liked to see a bit more meat for the price, but in the end, had a very satisfying meal.
