If you like ethiopian or would like a great introduction, Dukem is among the best in the DC area. Service can be slow when they're busy, but is usually very friendy. Their excellent, inexpensive vegitarian samplers top my list of great DC food. Some great marinated meat dishes round out the menu. Various people are trying to procure a "Little Ethiopia" designation for the neighborhood , and this restaurant offers a powerful argument. Nice outdoor seating in warm weather; easy parking in pay lot next door.
