The comments from Jason & Mike Colameco shed a lot of light to this topic. I've found that most Korean restaurants are just not as accessible to most non-Koreans & makes it more difficult for the cuisine to become popular. The menus are long with often unclear descriptions & waitstaff who can't clearly articulate them. I believe though that there is a trend happening now where Korean cuisine is being made accessible to non-Koreans without compromising the tradition of the cuisine. In Chicago, there are a couple of restaurants that have opened recently that exhibit this...a Western style menu, broken up into appetizer/salad/soup/main, etc., contemporary decor, an well-trained English-speaking staff, and even fancy Soju-tini drinks. There's Soju, Koryo, and Jin Ju, which is the only one that I've been to. I think they do a great job of bringing Korean cuisine to the masses and have been pretty successful thus far.
