I've never seen this truck at UofT, but I do see it in front of City Hall on the time on Queen Street West.
I love coming here for lunch. I like that there's a variety of options (hot dogs, sausages, hamburgers, chicken burgers). The meat is always a good side, and cooked well. I'm picky with fries, and I really like these ones. Always fresh, hot and well cooked. It's the cheapest lunch in Toronto. The service is always fast and friendly.
They have all of your standard toppings. I love that they also have the french fry seasoning and malt vinegar as well. Soooo delicious. I get the gravy (which is always free!) on occasion. It's just the right consistency.
