Harbour Fish and Chips, located in the Peanut Plaza in North York, is a tiny little joint usually frequented by students from the nearby Vanier high school.
It is mostly a take-out/delivery place, but there are a few chairs in the front. I'm not sure if you're supposed to sit there and eat, but nobody's complained.
The food is great, especially the halibut and fries. I always get an order of breaded mushrooms too. So yummy.
There's usually one cute little lady at the front that takes your orders, and she's always been fast and friendly with me. She speaks very quietly though, so you may need to listen closely!
If you're in North York and you're jonesing for some fish & chips, try it out!
