When I wanted good roti and doubles I used to drive up to the Drupati's on Albion Road. I'm told this is their newest location. It looks like they're working on some renovations but the decor is friendly on the eyes.
Conch roti and a potato and channa roti plus pear drinks.
OMG the best roti in town PERIOD!! Perfect roti wrap and right amount of spicy flavourful filling. Dang it's good!! Do it when you're in the mood.
