I've been to the Edmonton Julio's, and got addicted to their famous Bulldogs.
This Julio's specifically was not so great. One bulldog gave me a nasty headache the next morning, and I'm sure it wasn't because of the amount of liquor they put in. I'm basing my assumptions around the tequilla they were using, because it also tasted funny (even after flagging the waitress down to get another bulldog it still tasted a bit off).
The food was alright, I've had a lot better mexican food in my day.
All in all, I don't recommend it.
