We ended up trying this place due to positive reviews and it's slightly closer than our normal Korean favs.
On first impression the place seemed nice. You are greeted politely at the door and the restaurant is nicely decorated. From when we sat down it started going downhill. To start we were only offered three side dishes when you are normally provided with five or six. Even the kimchi wasn't very good, the sauce was too watery. We ordered the KamJaTang and KamPoonGi and rice was not included. Usually rice is provided with KamJaTang. We did check in for a free drink. That was a nice promotion but the prices here are higher anyway. Our food was decent but not great. It's not to the point where I would complain about the food, but I could list a handful of places that make it better so I don't think we will be return customers.
If service and cleanliness is a big thing for you, you may like this restaurant. But for me the most important factor is how good the food is, and SongCook is nothing special.
