If you're into home made Tzatziki sauce and generous portions, you would enjoy Astoria.
The restaurant is quite big - family style full of many tables and booths. We ordered two grilled calamari dinners and one pork souvlaki dinner. Each meal came with a large Greek salad. But I didn't like how the tomatoes were cut in extremely large halves and the lettuce was a bit brown.
I found the pork souvlaki to be extremely tough, even though it was recommended and the "specialty" of the restaurant. Grilled calamari wasn't all that impressive either. With each dinner, you also receive two sides (potatoes, rice, fries, veggies). My vegetables were overly salted and bathed in butter. The meal was satisfactory, we were full with lots of left overs.
Our waiter did a great job, meals came out fast, always refilled water glasses.
If it wasn't for the location of meeting West end friends, I'd probably just stick to somewhere on the Danforth.
