I've had many a taco in my life, and I can safely say that Seven Lives has the BEST TACOS EVER. Don't be disappointed by the line going out the door. It's worth the wait! If you're visiting Toronto/Kensington Market, Seven Lives is a must. We ordered two Baja Fish tacos and thought it was pricey for $5/taco, but once we saw the fish portion, we understood why it's priced at $5. It's a whole meal in one taco! The fish was lightly battered and crispy and stayed hot the entire time.
The only downside is that there isn't much space inside to eat, so if you see an empty seat or counter space, grab it! The next time I'm in Toronto, I will definitely return here to try another taco flavor.
