There's a 'Fortune Express' at the corner of Castlefrank and Hazeldean, right next to Dollarama. They have good dim sum.
A bit further down on Hazeldean, towards east, there's Hong Chow buffet, we like lunch buffet there because it's got a good variety of dim sum and sushi's, all you ca eat!
Staying on Hazeldean, but this time going west at the corner of Terry Fox, there's a good Cambodian restaurant if you like Thai and spicy food.
And if you like Vietnamese noodle/food, the Ox Head right across the AMC 24 theater is not bad..
