Culiacan has dozens of mariscos restaurants but El Guero consistently earns its reputation with locals who know. The aguachile negro — made with Worcestershire sauce, soy, and dried chilies to a deep, smoky version of the classic — is not what you expect and is entirely addictive. The ceviche is made fresh to order with whatever shrimp came in that morning.
The setting is simple: plastic chairs, checkered tablecloths, and cold beer served in frozen glasses. Order the combination platter if you want to try multiple preparations at once. Go at lunchtime when the kitchen is at full speed and the clientele is working-class Culiacanenses rather than tourists.
