During my first foray working in Pickering years ago, Roti N Ting was a mainstay for me, because their mini roti lunch specials were a tremendous deal for a filling meal.
Now that I'm back in the area, I wound up going back to see if it was still there, and if anything had changed. And nothing has, great filling food, roti is fantastic. They also do a number of other Trinidadian dishes, including shark and bake, palau, and they also make a pretty decent jerk chicken.
A safe bet for a quick cheap good feed.
