From the moment guests pull up, it’s not hard to tell that Don Juan’s Romantic Mexican Food opened in 1966. A certain brand of flashy midcentury Americana lights up every inch of the stucco building, declared a Grand Prairie Significant Landmark by the city's historical commission. Hand-painted signs—one shaped like a gargantuan sombrero—advertise “luncheons” and “dinners.” The menu hasn’t changed much, either: for more than 45 years, the cooks have been making chili, hot sauce, guacamole, and many other ingredients from scratch using the same recipes the founder perfected when the restaurant first opened. Tacos, burritos, and tamales join Tex-Mex favorites such as enchiladas, chili con queso, and taco salad in a deep-fried shell. For dining on the go or on the lam, the restaurant sports a drive-thru (one of the first in town) in addition to a robin’s-egg-blue counter with matching swivel stools.
