There aren't too many well-known Mexican restaurants in Toronto. At least not any I am aware of. So when I found out about Mariachi's, I was excited about going.
This place is fairly small. There's a patio in the back. The inside is a little dark and dingy, but it feels authentic. They give you a basket of nachos with salsa, which is quite delish. We ordered the veggie fajitas which were really surprisingly big. I think enough for two people, but I'm sure one person could finish them up. The servers were friendly, but they weren't that attentive, it wasn't even that busy the day we went.
