I've gone to the arrow a couple times to get a couple hours of working in. They have pretty reasonable coffee but by far the best thing about the place is the Montreal style bagels.
They don't make the bagels at the coffee shop, they are regularly delivered. This is one of the only places around Ossington and Dundas that has Montreal style bagels so it should get 3+ stars for just having them, but I've gone in a couple times now and their deliveries have been cancelled multiple times.
When they don't have the bagels, I've purchased other pastries that are unfortunately kind of stale.
If they would keep their pastries fresh, and the bagels flowing, I definitely think The Arrow could make a great alternative to ideal around the corner.
