I happened to be in Glendale on business and checked Yelp for restaurants that were running special deals, and found Koryo. Upon entering the restaurant my nostrils were assaulted by the strong smells of food cooking in a stuffy room with poor ventilation. After about 30 minutes my nose adjusted, but the initial whiff was unpleasant. The restaurant was sparsely furnished and could use an upgrade to get more business in the door, but otherwise was passable.
The service was friendly and the menu had standard items available in a Korean restaurant. The food, however, was the main event, and I wasn't thrilled. I ordered a Bim Bim Bop with beef and the beef was chewy and tasteless. The greens in my meal tasted fresh and crisp, but they could not save the overall tastelessness of the entire dish. I actually spat out the mushrooms because I had spent too much time chewing on them. The Kimchi was a similar disappointment. I definitely won't be returning.
