Chippy's has recently opened a second location at 490 Bloor West (at Brunswick, 416-516-7776). The other location is 893 Queen West, at Gore Vale, (416-866-7474).
The staff at the Bloor street location told me that they have a dedicated deep fryer for french fries. All breaded stuff is fried in a separate fryer. They also told me that the fries are fresh cut potatoes with nothing added. So, they seem to be gluten-free.
Here's a review.
