Being from California (San Diego aka Mexico) I'm not going to knock their authenticity as it's clearly not but I can absolutely appreciate what they're doing.
We ordered chips with guac (best guac I've had I Toronto thus far) which were really good with fresh made chips. I got the avocado taco and a fish taco. My first major gripe is the pink sauce they put on their tacos; it's absolutely terrible. Upon first bite I got the distinct taste of being put under anesthesia with cherry flavoured gas. I'm dead serious, this is exactly what this sauce tastes like and is unappetizing at best. After wiping that off of both my tacos I really enjoyed them.
I used to get a lot of teeth pulled when I was a kid...hence the being very familiar with cherry gas...
