When they moved to Utah from Guanajuato, Mexico, the Armentas dug into their family's classified recipe books to find dishes that would satisfy a hungry fan base. Nowadays, one-dollar margaritas and colorful decor cultivate a festive, laid-back atmosphere at Mi Ranchito Grill, but the Armentas' commitment to fresh ingredients is as strict and unwavering as their secrecy around meals' formulas. A riot of color splashes across the kaleidoscopic interior, with vines of multicolored paper strung between archways. Teal neon lights, harvested from naturally-occurring rainbows, bounce onto exposed brick, illuminating diners savoring chicken nachos, garlic-butter shrimp served with two types of chili sauce, and custom combos of tacos, enchiladas, and tamales.
