Tonight was my first time trying this Nak Won location. It took about 30 minutes to get our side dishes and an hour to get our meal. The table behind us left and didn't get cleaned until 30 minutes later and table in front of us started to serve themselves in terms of getting water and cups.
When the food got here, I was really impressed with the portion of my jajangmyun which cost 7.99.
The service could have been slow due to low staff or because it's Saturday night but still not acceptable. They have a call button at each table but don't bother pressing it because they don't pay attention to it.
