Back in 1964, the Herrera family turned an old Safeway into a Mexican restaurant and nightclub; although the party ended long ago and the kitchen now serves just weekday lunch and Friday dinner, the green chile is as sense-searing as ever, studded with pork and packing a spicy punch. Get it smothering a Mexican hamburger or a crispy-skinned egg roll-style relleno: This menu is Den-Mex all the way. While the neighborhood outside La Fiesta is rapidly gentrifying, a meal in this cavernous, linoleum-floored dining room quickly takes you back to Old Denver.
