This is one of the many gems in Kensington Market. If I ever had to recommend locals a place to try a variety of different of different restaurants, Kensington Market would definitely be one.
In terms of Seven Lives Tacos, let me preface it with the fact that I am not a frequent taco eater. I however, love seafood, so there is some prejudice in this. I really liked the tacos that didn't steal the show from the seafood, so like the Blackened Mahi Mahi, where I could taste the fish and the awesomeness of the spices. On the other hand, the Gobenator? uses cheese in it which made it taste like a steak and cheese and was totally not up my alley.
All said, I loved the tacos that showcased the seafood. The Tacos were small and good, and two was enough to make a meal. Typically, try the lighter seafood ones first, and only the heavy ones I would only recommend if you were looking for a full meal.
