Real Mex Restaurants Inc. announced Monday it will close six locations in Southern California, including the El Torito eatery in Burbank, according to media reports. The Orange County Register reported that Cypress-based Real Mex reasons for the six closures varied from lease expirations to poor performance. The company also owns the Acapulco, Chevy’s and Las Brisas restaurant chains. The Burbank El Torito was located at 3113 W. Olive Ave. near the corner of Alameda Avenue across from the Burbank Studios television production facility. Real Mex’s other closures Monday were in Los Angeles, Long Beach, Temecula, Torrance and Riverside. The company closed an El Torito Grill, a smaller version of the El Torito concept, in Sherman Oaks in October due to a lease expiration, according to the Register.
