Roommate and I had been wanting to try this place for a while and finally decided to go in today. The decor is fabulous!
I'm a little surprised people are saying the food was overpriced. I ordered a combo plate with an enchilada and a taco, my roommate ordered a combo of 2 chicken tacos. Both had huge portions of rice and beans, and the tacos were served with guac and sour cream. We each got a Diet Coke and the bill was $39 and some change, roughly $20 each before tip. The value of the food for the price was as expected, and not outrageously over priced - to those people I would say that if you can't afford to eat out, simply stay at home; cook and serve your own food if you don't want to pay for it.
As far as the actual food goes, it was very good. I've been looking for good Mexican food in Las Vegas ever since I came from California, I finally found it! :)
