Okay place if you can find it. Good roadside signage but I am sure poor layout of the strip mall that is why they have no lunch business. I found Koryo on Yelp and we were looking for the physical restaurant and still had a hard time locating the entrance. Nice wood interior but needs a good cleaning; floors, light shades, etc. The large floor fan helping to circulate the air conditioning was causing the overhead lamps to sway and knock dust onto our table. That was concerning so I got up and moved it a little. The dining room was empty for lunch time. It was hot in there too. Big downside to having your front door facing the sun in the summertime.
The staff/owner was really nice and attentive. Taking care to ask if we were familiar with Korean food. I don't blame him as someone new might send stuff back for being too spicy. They offered great lunch specials and had a nice menu selection.
For the restaurant being empty, the food did take a bit to get out to the table. The spicy rice cake is always choice and we asked for mild heat. The sauce was on point and good portion, but had no meat or green onion.
I did not care for the quality of meat they used in the Galbi bento box. It was mostly fat and not cooked properly. My mom didn't care for the chicken katsu, as the sauce looked burnt and was almost too dry to eat. The bento boxes were well dressed with an assortment of items: rice, salad, etc.
Ban chan was fresh and good. I wish I could give this place more stars but there were just too many things that add up wrong that all the friendly and attentiveness can't overcome. I really do hope they improve. I will return and try the Bibim bop instead and hopefully have a higher rating to update.
