I think this is the first of the Owl of Minerva chain of restaurants there are, but please correct me if I am mistaken.
I also think the lady who is the face of Owl of Minerva works here too but I have not asked fearing that it was impolite.
Excellent Korean food and extremely pleasant service. It may be a little hard to spot from the street but trust me, in its little Nook of the Chinese mall on Dundas and Spadina, you can't get better Korean food.
However, spice levels are not that high and has a very soothing effect on the palette - I recommend the pork bone soup and Kim Chi fried rice for the winters and their spare ribs and cold noodles for the summer.
Alternative if you're looking for spicy, spicy, spicy - read my review on Ka Chi.
