Located across the street from the Columbia Heights movie theater, Dragon House has served up Cantonese favorites since 1972. Specialties include pressed duck and Hunan dishes with fresh broccoli, peapods, carrots and celery. The staff is happy to customize orders and will deliver within a limited area. Dragon House offers lunch, dinner, carry-out and catering, but it is best known for its popular $6.50 lunch buffet.
