The Friendly Greek's food and service have impressed me the times I've visited. I'm no expert, but the food I've had here seems to be on par with some of the better Greek offerings in Toronto.
It would probably only rank 3.5 stars (if that was an option) but it gets bonus points for being one of the few places in the Yonge & Shepperd area that has good tasting, high quality food that is reasonably priced. It beats out Springrolls and all of the pubs I've sampled in the area.
They have a large menu and several vegetarian options, about 4-5 entrees (not just a veggie souvlaki folks). I really enjoy the vegetarian moussaka which seems quite difficult at other Greek spots in the city. The Saganaki (flaming cheese appetizer) is also quite tasty.
They have a couple choices of beer on tap and the casual service was quite attentive and friendly without being overwhelming or stifling. The owner seemed to recognize my girflriend and I after just a couple visits, which I always enjoy.
