Cafe Istanbul is located at 2001 L St NW. Their Web site says:
Our fascination with the cuisine and experience stems from Urfa Turkey. The cuisine is typical of the south-east; bread and meat are at the center either kebab, doner; particularly its distinctive mezes and kebabs.
But, our vision of the perfect restaurant has extended far beyond the actual menu. The atmosphere and décor play just as important of a part as the cooking; therefore, we wanted to provide a feeling of warmth and hospitality. We succeeded by creating dining areas that are as lively as they are sophisticated. A highly-trained and dedicated wait staff is another key to perfection, especially in providing diners with professional service and personal attention.
You can see their menus here. Could be a good late night spot as they are open until 4am on Sat. and Sun.? Any fans?
