Antigua Tex Mex is located in a small strip center in Suwanee. The 'on the rocks' margaritas are very tasty, but I don't really care for their frozen margaritas. I would consider their food to be better than average. The chicken dishes tend to be better than the beef dishes. One thing I don't really like about this restaurant is the slow service we have encountered on a couple of occasions. If the service was a little better, we would definately eat there more often.
