There is a local chain here in Albuquerque called Lota-Burger that most like more then What-A-Burger. They are OK but the best Burger's I have ever had are right here in New Mexico. Out on N14, headed towards Ceder Crest, is a little hamburger stand called Burger Boy. They server all sorts of different hamburgers. You can get a Bison Burger made from real Buffalo meat or you can get a Blue Cheese Worcesteshire Burger with Blue Cheese cooked inside the burger or you can get a Smoke Bacon Burger with Smoked Pepper Bacon or Hickory Bacon strips (not fat) that go about an 8th inch thick on your Burger but if you want my personal opinoin, the Green Chile Cheesburgers are as good as I've ever had. Half Pound of top ground, grounded there at the stand, with two pieces of American or whatever you want, grilled onions and fresh Hatch Green Chile chopped and seasoned with Garlic.
Really is as good as I've ever had. If you ever have the chance, you should stop and check it out. You'd be doing yourself a favor.
