The Real Jerk is one of the top roti places in the city. Being veggie, I highly recommend their lentil roti dinner. It'll fill you up and leave you enough for a second meal or lunch treat. The place isn't necessarily the fanciest or prettiest, but the staff is friendly and service is decent.
For meat eaters, the jerk chicken dinner comes highly recommended along with the combos that include jerk chicken along with jerk pork or ox tail. Everything on the menu is tasty.
They also do take-out which has been a life saver many nights on the way home from work. If I order as I get on the streetcar at Queen and Yonge I arrive just as my food comes out of the kitchen. Golden!
