I've been to Korea 3 times and spent about a year and a half of my life there. Korean food has never been a passion of mine, but good bulgogi (the BBQ-style dish cooked right at the table - "beef on a leaf" to the American GI) is pretty tasty. Most Korean bulgogi houses have a big charcoal stove that they use to create large, super hot coals that they bring to your table for the heat source. The meat, usually beef (sometimes pork), is sliced thin and marinated in a sweet, spicy sauce. When served properly, you take some rice, a bit of meat, and a few condiments (usually a spicy veggie mix and some sweet sauce), wrap it in a large lettuce leaf, and chow the whole thing down in one bite (lather, rinse, repeat until you're out of food).
Glibbidy, dunno if you've ever had true bi-bim-bap, but it's pretty nasty IMHO. The hot American version served over rice (bap) isn't bad, but the cold Korean version served with a runny egg over the top is just plain gross. It still appeals to some Americans, but not this one!
Kimchi is another Korean food I can do without. There are hundreds of varieties, and I really don't care for any of them. The cucumber version is tolerable sometimes, but not great. I love pickles, but the fermented vegetable smell/flavor of kimchi is pretty off-putting IMHO, even if the peppery spice mix is tasty.
