Not a good experience.
Went with a group that had previously made a reservation, and confirmed. The coordinator did follow up, there are witnesses. The place was not prepared, dinner took 2.5 hours, totally non coordinated, hard to get drinks, ran out of glasses, I could go on. The food was fair to poor, there are a lot of other places to get good greek food, such as Corporate Deli. Don't go to Kozani
