This place has plenty of seating and can accommodate large groups. The decor was interesting! It's located conveniently on St-Catherine.
There was plenty on the menu to choose from. My friend got the Mexican Flag Enchiladas (I think that's what it was called), and I got the Enchiladas con Mole. The food was pretty decent. Prices were within the $11 to $20 range.
Service was friendly and fast, especially considering how extremely packed and busy they were and how big of a group we were. Being an exchange student from southern California, I had been craving some Mexican food when I got to Montreal. I wasn't too disappointed.
EDIT: My friend from Spain and I came back for their $0.69 Taco Sundays. All day Sunday, you can choose between chicken, beef, chili, or veggie hard-shell tacos but can only order 4 of the same kind at a time. The catch is that you have to buy a drink. You also have to dine in to take advantage of the deal. My friend from Spain loved the tacos. Our favorite was the chili. The meats for the other kinds were hardly there and not very flavorful. Their apple in fried flour (forgot what it was called) dessert was amazing!
The food is average and somewhat pricey, but I'd definitely come back for the apple dessert!
