This is my favourite Greek restaurant in Toronto. The calamari is unmatched with any other restaurant that I've seen (never stringy and horrible like it usually is) and even more delicious when accompanied with their creamy tzatiki sauce.
The chicken kleftiko is an invention that I never knew of until I went there. Its a chicken breast with tomato, feta and spinach wrapped in filo and its quite a treat.
Also I would strongly recommend the spanikopita and the beet pies which are individually cooked to order and much much better than any other spanikopita that you might eat at a bakery that's been sitting around.
