I have lived most of my life in Europe, mostly Athens and London. This restaurant is good. The food would be considered generally average in Athens and probably a little above average in London. However, I am not a huge Greek food fan. One person mentioned that moussaka was like a Mediterranean lasagne. Well, surprise, it is. It is only cooked with egplant instead of pasta. It is strange that those from large cities like NYC and San Francisco compliment the place and those from the local area criticize it. I suppose that if you compare Greek food to what you usually eat at home, it won't be good for you. But, if you like Greek food and compare it with other Greek places, you will see that it might not be the best but it is certainly comparable to that in the motherland.
It is a good place to go with friends in a casual setting, and the price is pretty reasonable. Don't compare, just enjoy the food.
