Dona Maria's downtown on Las Vegas Boulevard makes some really tasty Mexican. It's very authentic and casual. I went last night and had the tamale plate special--$10. I had one pork and one chicken; served in enchilada style. The chicken had a green sauce and the pork had a red sauce. It was divine. I'd really didn't care for the margaritas, but I'm pretty fussy about them. My friend had a gorgeous chicken tostada. You need to ask for the extra hot hot salsa. I would highly recommend this place.
