Perhaps it's because I'm Italian that I have a biased towards Joe Panini. I grew up eating real authentic paninis from local bakeries in east end Montreal. I have very high expectations when it comes to the quality of the bread, cold cuts, cheese and pickled toppings. Simply put, Joe's panini just doesn't cut it for me. They're sandwiches are ok, decent at most. Nothing to rave about to be honest, everything is pretty basic.
On the plus side, they are open 24/7. Therefore if you're downtown late and hunger strikes, you could always head here.
