I was a regular here during grad school. It was the closest thing to my mother's cooking back in Seattle. I just didn't have time to cook for myself during finals week so I hit this place every other day. I highly recommend their Jung-shik courses. It comes with rice, bean paste soup, side dishes, and fried mackerel fish. I found this to be the most well-balanced meal for those needing to meet the demands of school. I have heard about the customer service being a hit or miss and that's cause you don't speak Korean or you always expect amazing service without tipping well.
My suggestion: tip well and they will remember you. Because I knew they were a primary supplier for my Korean fix, I wanted to show them I valued their business. It worked. They remembered what I ordered, I was always seated promptly during busy times, and the owners were never rude to me. I often came alone and they always still cared to ask how my food was-which was always great.
I give them 4 stars out of 5 because they close on one of the weekdays, I forget which one. I even forgot when I lived there so I often drove out for no good reason. hah.
