Bannock was one of the first places I ate at when I moved to Toronto, and it has had a special place in my heart ever since. If you haven't had bannock before, the bannock bannock is a great introduction. Or, if you really need a pick me up, get the ridiculously rich duck poutine pizza.
It's reasonable prices, can't-go-wrong "Canadian comfort food" menu and central downtown location make it a destination. The service, as with any O&B establishment is always top notch.
