Costa Mesa-based El Pollo Loco Inc. said it has hired a Bay Area ad shop for its general market and Hispanic accounts, ending an agency review that began in December.

Sausalito-based Butler, Shine, Stern & Partners will handle creative duties for the grilled-chicken chain’s branding and other communications.

The agency’s initial work for El Pollo Loco is set to debut next month.

Butler Shine’s client roster includes Woodcliff Lake, NJ-based BMW of North America LLC’s MINI Cooper along with AT&T Inc. and Greyhound Lines Inc., both of Dallas, Tex.

El Pollo Loco launched an agency review late last year following its split with Hollywood-based ad agency goodness Mfg. The two parted ways less than a year after the chain hired the agency.

El Pollo Loco counts about 400 restaurants, mostly in California and neighboring states.
