Cheap, delicious, and filling.
For students: $6 combo gets you a large chicken shawarma, soft drink, and fries.
I always have one thing when I'm at Osmow's, their 'Chicken on the Rocks'. There are always left overs, and you can easily share it with two people. Also, if you don't feel like eating the over priced frozen food at Scotiabank theatre, you can always sneak in some Osmow's :P
