Located in a nondescript plaza off Dundas, Man Doo Hyang is a popular Korean restaurant and a great way to experience Korean food beyond AYCE BBQ.
The name of this restaurant translates to Dumpling House, and these dumplings certainly don't disappoint. You can order them fried or steamed; I prefer the latter as I find it lets you taste more of the dumpling. Note: the soy sauce/chili for the dumplings is contained in a tiny squarish porcelain jar with a lid to the side of your table.
We rotate through a lot of options when we come here, so I'm entering list mode:
1) For groups of two or more, the Kam Ja Tang is popular here. Unlike other restaurants, the pork bone soup is brought out on a burner and cooked at the table. Koreans seem to possess the inherent ability to consume liquids while on the boil...I prefer to preserve my taste buds. If you want to sound like a snob, make a comment to your table on the potatoes, as they're specific to these Korean dishes.
2) Typically bulgogi at restaurants is horrible, and one of the cheaper meat options. Not here, where (again, cooked at the table), the bulgogi is thicker, flavourful and delicious.
3) If you're not looking for group items, try the Handmade Noodles with Dumplings in Beef Broth. This soup has a deep, rich flavour to it and is very satisfying. Add the ddok (rice cake medallions) if you want more starch.
4) For something different, you could try the Jajang Myeon. Derived from a Chinese dish, these noodles are smothered in a thick (really thick) black soybean paste, minced pork and veggies. I typically can't finish a whole order myself (it's thick stuff), but Koreans can wolf this down like school girls at a Big Bang concert. Ask for scissors to save your wrists from chopstick-related strain.
The service can be hit or miss (I find there's a revolving contingent of young Korean males with varying degrees of competence), but don't be afraid to wave down anyone. Older Korean men typically don't give a damn and just shout out what they want. You could use the service bell glued to each table, but these are only responded to half the time.
