Where can I find authentic Mexican cuisine in/around Las Vegas?  I'm looking for something truly Mexican. It doesn't need to be fancy, just good. The best I've had so far, is a restaurant somewhere in Utah. We were coming back from Bryce Canyon and stopped at a beat up old house that had a beat up sign out front that said "Restaurant". The food and service was unbelievable! very casual but first rate. I don't mind driving a ways to find the right place. Thanks for any suggestions.
