I would call Amaya Express the McDonalds of Indian food in Toronto. It's not the best, but it's also not the worst.
Pros:
Clean
Tidy store front
Seating
Friendly staff
Fast take-out cuisine
Inexpensive
Nice takeout containers (I'm definitely going to reuse mine!)
Cons:
Add ons are pricey (watch out ~$2.50+tax for naan)
Simple food
While the food wasn't overly flavorful, it was very quick and reasonably priced. I don't think it's fair to expect sit down quality food at what is basically the drive-thru of Indian food.
I would go back again if I were in a hurry and in the area.
