I went to this Joe's Panini at about 4:00 am Sunday morning after a long Saturday night in Montreal and there was still quite a line up of people.
The line moved pretty quickly though. These guys got it down to a science! I ordered a grilled chicken Panini which came to $6 (including the $0.50 fee for Interac). A real bargain.
I do realize I went at an odd hour but the food was sub par. The chicken was very dry and had minimal toppings.
In short, service and price were great. The food itself knocks it down a notch for me though to a 3 star rating. If you're in a pinch for food and running out of cash and or time, Joe Panini will do but I'll do a bit more searching for something a bit tastier next time...
