Probably the best all-around Korean restaurant in Greater Toronto Area without a doubt.
Food-wise, SongCook's dishes are as close to authentic & delicious home-style Korean cooking you can get. Classic dishes such as JangJamyun (black bean noodle), kkanpunggi (deep fried pork sweet sour) or simple dishes such as bim bim bap are prepared executed flawlessly. If I have to nitpick the food - only their soon tofu last time I tried was not up to par (a little too salty)
Service-wise, I have not encountered any Korean restaurant to have better service than SongCook's (this includes pricier Korean restaurant such as Sariwon). Service is of the highest level of being gracious while at the same time efficient and attentive.
At this point - I should concede and give up already finding a better Korean restaurant than SongCook's. Can't recommend enough of this restaurant to any friends and family who are looking for a solid Korean food pick.
