Diego's Mexican Food in Alpine runs a drive-through taco shop at 1140 Tavern Road, sharing the Shell station lot at the Interstate 8 Tavern Road exit with Caffé Adesso's coffee bar. The kitchen builds a 13-item combination plate menu around shredded beef tacos, cheese enchiladas, chile rellenos, tamales, and chimichangas, pairing each plate with rice, beans, and tortillas in a format distinct from the craft-beer-paired Mexican fare at Mcilhenney Brewing Co. on Alpine Blvd. San Diego County's Environmental Health division assigned the kitchen a 98-out-of-100 inspection score, placing it among the highest-graded food establishments in the Alpine zip code. The carne asada plate arrives with steak smothered in guacamole and house chunky salsa, while the machaca plate scrambles shredded beef with onions, tomatoes, bell peppers, and eggs for a Northern Mexico-style preparation. The drive-through lane handles the bulk of orders from Interstate 8 traffic, supplementing the Tavern Road corridor's beverage options at Alpine Liquor on Alpine Blvd with a full taco-shop menu accessible directly from the freeway exit. The steak ranchero features thin-sliced beef cooked in house-made salsa ranchera, served with rice, beans, and a choice of corn or flour tortillas alongside the carnitas plate's slow-cooked pork in chile verde sauce.
