There's a very nice Korean restaurant called Seoul Garden in the Pacific Mall (Kennedy & Steeles). The entrance is easiest off Steeles as it is on the south side.
It has a lunch and dinner barbecue menu at about $12 and $15 respectively.
Lunch has barbecue: beef ribs (kalbi), marinated beef (bulgoki), spicy pork, chicken, and squid. Dinner includes shrimp (head on).
It comes with a very nice and hearty version of a miso - based soup. As with all Korean meals, lots of side vegetable dishes.
The barbecue is excellent. They bring the raw meat to your table and you grill it there. The barbecue is nice because it has charcoal as well as fuel to give it a nice authentic taste. After the first plate of meat, they will ask you what you'd like on the second plate, so you can change the proportions or eliminate something (like the squid - which although good, sticks to the barbecue). They change the bbq plate frequently and the service is very pleasant and attentive.
Decor is surprising and nice though a bit odd - like you're in an Italian courtyard.
Be aware, that if you come with a group if people, they everyone must have the barbecue. If this is a problem, just tell them the person who doesn't want the barbecue is vegetarian and they back off. Their other food menu choices are quite good - I like their jampong which is a spicy seafood noodle soup - the real version of the instant noodle Spicy Neoguri.
