This place was recommended to us by some friends who said that the food was good but they hadn't been there in awhile. Well, it may have been good a few years ago but Garduno's is definitely nothing I'd recommend to a friend.
The food actually wasn't that bad - it was mediocre at best but still edible. Then again, it's hard to screw up a cheese enchilada. My chile relleno was covered in about 2 inches of breading that wasn't even fully cooked. The tableside guacamole was good, though.
The service was comically bad. Our server was such a jerk that we just had to laugh about it. From refusing our requests to giving attitude to everyone at the table (including a polite child), he was one of the worst servers I've ever had.
The company was good but the food and service was way below par. There are many other Mexican restaurants in Scottsdale - try any of those.
