The bar/food scene in Kensington Market is absolutely nuts. There's so many good places, it's impossible to list them all off the top of my head.
Even amongst stiff competition, Rasta Pasta deserves high praise. I've eaten here maybe half a dozen times since first discovering it and every single time, I've received phenomenal service. Everyone is super friendly and passionate about the food that they serve.
Speaking of the food, it's awesome. As you can probably guess by the name of the establishment, they try to fuse Caribbean and Italian cuisine together. Sounds odd but it works surprisingly well together. The portions are huge and they don't just try to fill you up on the pasta/rice either.
Don't sleep on Rasta Pasta!
