Al Pastor PapiA-

232 O'Farrell St, San Francisco, CA 94102 · Mexican restaurant · Union Square

Flavor-first Mexico City style tacos and burritos near Union Square with lively vibes and fast-casual service; excellent pastor, moderate prices for downtown, minor consistency and crowding issues.

The verdict

Al Pastor Papi earns its A- grade through exceptional food quality—a properly executed trompo with crispy caramelization and bold salsas—paired with responsive counter service and strong local appeal near Union Square. Occasional consistency dips and a modest dining environment prevent the higher grade, though the fast-casual format and fair value make it a competitive neighborhood destination for quality pastor tacos.

About this restaurant

Steps from Union Square, the room feels lively and casual with hip-hop humming and trays of tacos moving fast. Reviewers rave that the pastor is sliced off a proper trompo and the staff keep things upbeat. One guest put it best: "Flavor hit hard, and I was out the door fast." The cooking leans Mexico City street-style—gringas, vampiros, generously filled tacos—with a focus on texture and caramelization rather than fancy tricks. Expect crispy edges and bold salsas, plus rotating horchata flavors. Most find the value fair for downtown, though a few call out pricey burritos and the occasional dry cut of pastor. Families do well here thanks to simple tacos, bowls, and friendly staff. A parent noted the team even put on a movie to help their kids settle. If your crew prefers mild flavors, stick with chicken or asada tacos and the less-spicy salsa, and share a gringa for a cheesy win.
