I may be a little biased towards Korean restaurants in general, but this is the kind of restaurant I hope to see in a foodie town with a huge Korean presence. The staff was all quite friendly, the bulgogi, chadol baegi, and all of the banchan were just right, and a regular A+B order was very filling and satisfying without the "stuff yourself until you aren't even enjoying it anymore" aspect of AYCE hanging over my head.
Some places try too hard to be absolutely perfect in one area and forget others. Arirang doesn't try to revolutionize Korean BBQ, they just do every single part of it well and that's worth something.
