Best Korean Food in Beijing by Far

I don't know much about Korean food outside of Beijing I never had it back home. I know this: Iki has ruined other Korean food for me. Other places I used to enjoy I do not enjoy any longer because this place has set the bar so damned high. I can only guess that this is authentic Korean food and everything else Ive had in Beijing is a poor imitation.

If it is not authentic Korean food, then they have their own incredible cuisine in its own right. I wish I could give them six stars. I also wish I could afford to eat here more often. Its not overly expensive and its worth the price, but I cant really justify eating here as much as I would like to.
