This was my favorite lunch spot in Montreal. My wife and I were there on a busy Saturday and only waited 5 minutes to be seated. The system is very simple. You order your food at the counter in the back then sit down and wait about 15 minutes for it.
I had Le Cubain (ham, braised pork, homemade mayo, and gruyere cheese in a panini) and a bite of my wife's Poulet de Grain Cajun (chicken, guacamole, tomatoes, mango fraiche and cajun spices). Both were delicious with lots flavors going on and a little kick from the spices. We each had a glass of their vanilla lemonade too. I'd never had vanilla lemonade so I didn't know what to expect but I liked it.
When you're done you pay at the register while getting an almond croissant to go. You must not leave without one! Especially if it's Saturday because they're closed on Sundays. Their croissant flat out embarrasses the Almost Twist bread at Taipan Bakery in Flushing.
