I've been to Spot plenty of times in the morning en route to work and the service has always been friendly and prompt.
I've taken a run at the omelette breakfast that comes with a bagel, and while I think its a tad bit pricey, it's still deliciously good. For those with a larger stomach then I, you'll be plenty full.
Spot also has a generously sized patio, maybe one of the biggest I've seen in Toronto for a coffee shop and the wifi out there is as good as your living room.
