The menu printed in six languages
If the menu comes in English, German, French, Italian, Russian and Chinese, and a man outside is waving you in, keep walking. That one rule clears most of Plaka and Monastiraki. Those tables are set for people who will not come back, and the kitchen knows it.
Instead Eat where Athenians eat, in Pangrati or Koukaki, a fifteen-minute walk or a short tram from the ruins. No pictures on the menu, a full room after nine, a raki you did not order.
