I thought it was quite good. It's more like a 3.5 but I will upgrade to a 4. I really enjoyed the Tangsooyook. The JapChae was average-I could have made something similar. I liked all of the side dishes and we got 6, I think. For the price, it was fair. I saw other people with the hot pot to share and that looked really good.
The service was fine, nothing to write home over but it was fast (within 15 minutes, maybe 10?)
