"Cancun (with three locations in the Mission, Bernal Heights and SoMa) is a San Francisco crowd favorite. If you’re deciding what to order, the al pastor and carnitas are always reliable and the tacos always have just the right meat-to-tortilla ratios." - Paolo Bicchieri, Dianne de Guzman, Eater Staff
