The vibe: Inside, the sights and scents of al pastor hit with a pleasant intensity. Sit at the counter facing an open kitchen (preferably closer to the pastor trompo for a good view) or the small adjacent dining room. Both are first-come, first-served. After sunset, the bright yellow neon signs radiate the powerful message behind Guerra’s business: “More tacos, less borders.”

The crowd: Frontera aficionados regularly walk from their nearby homes or stop by for a quick bite. Friends and family visit in small groups; lone diners stop in for a meal that takes less than 30 minutes from start to finish.
