At Santa Rosa Taqueria, the sight of the trompo signals a dedication to classic street food. Slices of al pastor are carved from a vertical rotating spit for tacos, with the marinated pork stacked high with pineapple chunks that caramelize as they cook. This commitment to traditional preparation is at the core of the restaurant's philosophy, which is centered on the Capitol Hill neighborhood it serves. The selection of dishes expands on this foundation, offering modern interpretations of Mexican flavors inspired by popular street foods. The food revolves around familiar items, including handmade tacos, queso, and nacho platters. The kitchen has become known for variations like a barbacoa taco with beef short ribs in a 5-chile mole and a cheesy birria taco served with its consommé. This fast-casual spot has evolved, adding more substantial plates suited for a longer stay and a happy hour that draws in local crowds. A veteran local mixologist designed the beverage program, which features an extensive list of creative margaritas with flavors like guava mango, complementing the fresh ingredients of the food. Located on Pennsylvania Avenue, the Washington establishment cultivates a fun, bar-like atmosphere that its neighbors were seeking. The two-story space features vibrant colors associated with Mexico, including turquoise tiles and a large mural inspired by the Day of the Dead. With a spacious dining room and an equally large outdoor patio, it provides a lively backdrop for a casual meal.
