Dona Maria serves her margaritas with Cuervo Gold and she sells her hot tamales by the dozen. And they go, by the bushel full, in four flavors. Red is pork tamales in a mild sauce, an order of green is chicken in spicy sauce, Sweet brings pineapple and raisins to the mix, and classic cheese is made with Monterey jack and green chilies. Of course there's other stuff like the usual nachos and tacos and burritos and fajitas, and it's all good served in a room of champagne pink and lime green with boxing posters all over the walls. Dona Maria has been serving up her tamales here since 1980. That's a long time by Las Vegas standards, where resort hotels are given 20-year life sentences. She still manages to pack in the lawyer, police and biz crowds by day and hard-core tamale lovers by night in the restaurant's downtown location between the Cupid Wedding Chapel and Gateway Motel, selling rooms for $26. Dona Maria Tamales Restaurant, 910 Las Vegas Blvd., 702-382-6538.
