I would recommend it as they do get busy. Though it is not required.
I'm not sure it's mandatory, we did. It was Saturdays night dinner and it was not overly busy and also waiters did not present greek dance as mentioned by other viewers. Very disappointed bc that was the main reason we went there.
Dinner can be busy so I would recommend a reservation.
For dinner it would be in your best interest to reserve a table
