Just discovered this gem in the BWV neighbourhood this past month - according to the server it's been around for 10 years! I'm generally hesitant about trying these kind of smaller establishments, but boy am I glad I ever did. I've been back again this month and each time the servers are amazingly friendly, the atmosphere fun and has authentic Mexican and Colombian dishes.
The drinks are delicious - I've had a strawberry daiquiri and sangria - and although the food hasn't been to my taste both times, I am definitely going back to sample more on their menu. The first visit I got a Colombian dish recommended by a fellow Yelper. The second visit I got flautas which are hard corn tortillas - unfortunately I like soft corn tortillas - my bad I should have asked. The food isn't the cheapest, but the price of the drinks more than makes up for it.
Definitely worth checking out if you want a place that has more character (and is much more lively) than the run of the mill fare on Bloor St.
