Check out this link to read about the general characteristics of Korean food. Also, these two sites have cool recipes for those of us who have kitchens in our dorms. This guy seems to have the ultimate kimchi recipe.....For a recipe that is 7 pages long, it must be good!
I don't think there are any Korean restaurants in Washington DC but there are a few outside the city.
Two sample recipes:
Barbequed beef--Barbequed beef ("pulgoki") is the one of the most popular dishes in Korea, and also Westerners are pleased with the taste. "pulgoki" literary means "fire beef", but it is called generally called "korean barbecue". Thin, tender slices of beef are marinated in a sauce and cooked over a hot charcoal grill at table.
Rice Beef Noddle Soup--"Sollongtang" is rice beef noodle soup seasoned with sesame seeds, salt, pepper, scallions, and sesame oil. It is served with rice as the main meal and is accompanied by side dishes and a radish "kimchi" called "kaktugi."
P.S. If you go through those sites, you will be hungry...... :)
