I've been to A-Ri-Rang several times now and I have to say that I am not a fan. None of the dishes are particularly great, and I would even dare to say that most are vastly bland by Korean standards (my S. Korean friend really didn't like the beef bulgogi).
Being that it takes a very long time to get your food, and that finding seats for groups larger than 2 people is nearly impossible, I am not likely to return -- There are definitely better Korean restaurant in the extreme vicinity.
