I found the most authentic Jamaican cuisine in the GTA made right here at Nicey's. It may not be located in a popular area, but the line up goes to show the amount of people impressed with their food!
Some of the must-order items include the jerk chicken and the ox-tail.. (I'm now drooling as I type this) accompanied with awesome rice that's also packed with flavor that will deodorize your car. The ox-tail is my favorite item - the meat is so tender it falls right off the bone. It's simmered in spicy gravy that goes really well with the festival (which are ONLY $1 each).
Overall, the prices are very fair for the quality you get. Beef patties on display are only around $1, what a deal. Exotic drinks like "Sky Juice" and other labels you won't usually find elsewhere can also be purchased.
I highly recommend Nicey's if you want to indulge in some authentic Jamaican cuisine made with love.
