At one point, Nak Won was my favorite Korean restaurant and I was proud to bring friends and family to eat solid Korean food with decent service but that time has long gone. Last time I frequent this establishment in May 2014 the service has gone to a deplorable level.
Me and my friend simply made a request for a side-dish refill - and asked again as we have not seen in for quiet sometime - and the server simply yelled at us "It's coming!" and the server who brought our side dishes were grumbling in Korean which we did not understand. You could have eaten in a prison cafetaria and you might not notice the difference of the service quality. That would be the last time I eat at Nak Won.
