One word: Margaritas
This is my favorite place to do some afternoon drinking in the sun. They have an awesome outdoor patio and the best margaritas I've had in Toronto thus far. The guacamole (the spicy version) is really good. Not too spicy and has good flavor. Everyone that I have taken here agrees that the drinks are awesome.
I have not eaten a full meal here, so I can't really comment too much on the food. We shared the chicken tacos last time I was there and they were pretty good. The food seems like it's made with fresh ingredients and is nicely spiced.
It's a popular place so there can be a long wait --try to go before or after the rush so you don't have to wait long.
