This Arouch is in the JMSB building in Concordia... and is full of students running to and from classes. They offer a variety of pitas (I usually get zatar - a mix of thyme, oregano, sesame and other spices), with or without additional cheese. They heat up the pita, then take it out to top with your choice of toppings, including lettuce, tomatoes, hot peppers, mint, pickled turnips (which I LOVE), olives.. etc. It's $0.40 per topping and around $3-ish for the basic pita (if my memory serves me correctly..)
The pita is rolled up into a nice portable sandwich perfect for eating on the run.
