Bairaktaris ★ 3.9
Bairaktaris on Monastiraki Square in Athens runs until 02:00 every night, the long-running souvlaki counter that has fed the after-bar crowd since the late 19th century.
Try: Souvlaki and gyros pita
Order: A pork souvlaki pita with extra tzatziki and a glass of the house retsina.
Tip: The pita window faces the square; the sit-down room behind is a separate bill and longer wait.
