The Rudy Burger is the closest thing to a Shake Burger from Shake Shack that I've been able to find in Canada. I just can't get enough. Best burger in TO (and these are bold words coming from a longtime Burger's Priest fan).
The deep-fried pickles are also delicious. Poutine is hit or miss (sometimes it's melted mozzarella instead of cheese curds). But if I wanted a killer poutine I'd go elsewhere!
