La Posta is one of the grand old Mexican-American restaurants of the Southwest, serving such classic New Mex fare as tostadas compuestas, which is a crisp-fried corn tortilla cup into which is ladled red chili con carne, beans, cheese, lettuce and tomato. A sort of prototypical supernacho, these hearty cups come three to an order for dinner, or as one part of a combination plate that also includes a chili relleno (a large cheese-stuffed, breaded, and deep-fried chili pepper), and a taco as well as guacamole salad.
