It is very rare that ancient greek plays are performed in ancient greek. It will be like being in england and performing a play in latin. There is an education / novelty factor but hardly anyone understands anything. Ancient greek plays are performed in modern greek tranlsations and are produced like any other play. It's down to the director how many ancient greek elements they want to keep at the production. Comedies are modernised much more than tragedies.
Your chances are much better during the summer, May to September, check the Hellenic festival in Athens and Epidayros, the productions are any performing art from all over the world, but there are always ancient greek plays. Also, during the summer, several productions will be touring the many open theatres in greece.
