I have gone here twice with family and friends on visits to Toronto, both times were similar experiences. It's a big restaurant and pretty quiet, the place reminds me a bit of a ballroom. It seems like a place people might have wedding receptions at.
The waiters came to our table within minutes of us sitting down. While attentive, I had the impression that they didn't want to be there, and just wanted to get things done and over with.
Anyways, the food: dinner started with some garlic bread and a generous portion of Greek salad. Nothing special about the salad, I would say the bread was better. My sister ordered the hot appetizer plate for us (we were a group of 7), and that was just ok. There was some calamari and spanakopita, to what I remember. After the appetizers, I was already getting pretty full.
I have tried the spanakopita and the pork souvlaki as the main dish on separate occasions. Both dishes come served with some rice and vegetables. The spanakopita was good, the souvlaki and the vegetables were dry. Most of us at the table were unable to finish our meals, and ended up taking the rest to go.
For dessert I tried the baklava, which was good as well, probably the best part of the meal.
Not really authentic Greek food, but passable. I would go again if invited by my family, as they really seem to like it, but it's not a place I would go back to on my own decision.
