We weren't sure what to expect but were told to try it out.
Basically you pay a fixed price for a set meal.
We were a party of 2 and the meal we got was absolutely huge.
The highlight was a selection of starters, many of which were really tasty. This was followed by a meat pasta dish and a lamb dish. Both were ok. Then we had a large selection of fruit and some greek yogourt for dessert.
Our meal came with wine and unlimited soft drinks.
There is also greek music and dancing with audience involvement.
Overall it was a good experience, probably best if you are in a reasonably large group.
