This place serves the best roti I've ever had (and I say this as a woman who sought out lots of obscure places around the city). It's a take out only place (although they sell jar of jerk spice and the like), it's located in a dilapidated strip mall, and there is no bathroom. It's run by Barb and her husband Patrick who are from Guyana. There son helps out at the shop as well.
There homemade bread is soft and spectacular. I especially love the no-bone goat and jerk chicken rotis. You can wash it down with some Ting.
Beware, the owners have mixed feelings about how popular they are amongst self-described foodies. They close at 7 pm, are not open Sundays or Mondays, and close down for about a month each year around January/February. As well, there are a lot of signs on the walls saying things like 911 was a conspiracy. Indeed, this offended a very right wing Bay St. tax lawyer I once dated who upon arrival just as quickly walked out. I thought he'd seen a rat or bug or such. No. He just disagreed with their politics.
So if you're on the QEW passing Cawthra or Dixie, you might want to check it out. There is usually a 5-10 minute wait to get your food after you order.
