Greeks rarely eat alone — meals are extended social events. "Opa!" is shouted during celebratory moments, not just plate-smashing. It's polite to leave a little food on your plate to show you've had enough. Coffee is served after dessert, never with it.
Παρακαλώ (parakalo) — Please / You're welcome, Νόστιμο (nostimo) — Delicious, Τον λογαριασμό (ton logariasmo) — The bill, Γεια μας (ya mas) — Cheers, Ευχαριστώ (efharisto) — Thank you
