Margarita's

OK, it is well known that there is a dearth of authentic Mexican restaurants in the city of Toronto. There is lots of Mexican food, but most of it is along the lines of an echelon above Taco Bell, which isn't saying much.
Margarita's is one of supposedly hipper joints to eat Mexican, seeing as it's survived a really long time on Baldwin. And they do make their own tortilla chips, which is nice. But there is still something lacking in the authenticity. I think when you can offer fried calamari and caesar salad on your menu, do you truly believe in your own ethnic cuisine?
I had a (massive) glass of sangria, which was more sweet than wine, and ordered the enchilada with mole sauce. Now, the mole sauce wasn't bad, but it was hard to pick out the chocolate and the chili in it... like, you couldn't pick out: "Ah! There's the cocoa!"
Service was also a bit, ???. One of my dining companions was late, and asked that we pre-order for them. When we stopped out waiter to ask to order her food, we were told, "Well, the kitchen is really busy right now"..... What???? Isn't the point of a restaurant to be busy?
