Wow. Run, don't walk, to this place.
I usually avoid food court restaurants like the plague, especially around tourist traps like Yonge-Dundas square. But this hidden gem is the real deal. Incredibly delicious and complex Indian food at an amazingly reasonable price point. For $7.50 (!!!!!) I got a heaped serving of tender, rich, spicy yet flavoursome lamb curry, a side of delicious spinach and potato (it's not listed on the menu, but you get a veggie side with every order of a meat curry - such good value!) and a piping hot, soft and fluffy naan baked fresh in an actual real-deal tandoor (oven) that they have managed to set up in their tiny space. Service was fast and super friendly and ready to please.
Seriously, this is some of the best Indian food I have eaten in Toronto. My mother and father ran an Indian restaurant when I was a baby and I was nourished on chicken Madras while I was in utero so I like to think I know what I'm saying when I say... this is the real deal. Get to it to people!
As others have said it is hard to find: it's on the third floor of the Cineplex complex at Yonge and Dundas (on the north east side) and it's kind of hidden away in a corner near the bathrooms. If you are coming out of a movie you will see it immediately on your left as you enter the food court. Remember not to fill up on popcorn, because Curry and Co is the real treat! (Note for parents: kids love the mango lassi).
