Zaytinya

Greek tapas, also called Mezze or Meze, which "is a selection of appetisers or small dishes taken with alcohol, similar to tapas of Spain (Turkish Meze from Arabic: مزة; Greek Μεζές, pl. Μεζέδες; Bulgarian, Serbian, Macedonian мезе, Montenegrin Meza, Russian Закуска‎), in eastern Mediterranean, Bulgarian and Turkish cuisine"
The food here is...in a word....DELICIOUS. The atmosphere is great (though can be a little noisy), but well worth the trip. If you visit, you should definitely make a reservation. Reservations can be made by calling (202) 638-0800 or using Open Table. You can either eat at the bar, which is just as good as getting a table. I HIGHLY recommend this place!
