I only know of one super good Korean Restaurant that my friends recommended years ago and it continues to be the only one I frequent: Ho Soon Yi. There are two branches - one in Edmonds off hwy 99 and one in Tacoma off S. Tacoma Way. It's popular for soon du boo (sp?), a spicy tofu soup. I also recommend the meat dishes, fried mackerel, and pah juhn (scallion & seafood pancake). The side dishes are great and are almost a meal in itself. Yum! It always satisfies my craving for spicy Asian cuisine! Love it! Make sure you go there hungry and early, as the north end one can get very busy.
