I think the point of this exercise is to expand the range of offerings at the street carts. Until now the variety of food has been extremely limited. I look forward to a better selection this summer.
I have eaten hot dogs from the street vendors many times and never had a problem. I like one of the trucks that parks on Queen Street directly in front of City Hall. They have very good fries. I also patronized a couple of them at Queen and Spadina last summer, when they had a price war at that corner and seemed to be selling hot dogs at cost, or maybe even less. Not sure if that is still going on.
