Ka Chi is another excellent Korean restaurant in Chinatown on Spadina approximately a 5 minute walk from Dundas and Spadina.
Excellent food and service - I would recommend the pork bone soup here, the seafood omelette, the Kim Chi fried rice, and any of their skillets.
It is particularly spicy for the average spice consumer but is worth every bead of sweat. I normally come here during the winters as the summers are too hot for me and this spice level - if you like it, by all means go for it!
Alternatively for a lower spice level, please refer to my review on Owl of Minerva which is walking distance away.
