We're often a little skeptical, but typically quite willing when it comes to all-you-can-eat buffets. Frida Westwood, the new name for chef-owner Vicente del Rio's nearly one-and-a-half year-old Caza Azul, just launched a new AYCE mariachi brunch buffet on Sundays from 10:00 A.M. to 3:00 P.M. Practically giving away food at a $20 price point, it's hard to imagine that even buffet-phobes won't be won over by an impressive Mexican spread that includes tamales, guisado de nopales (cactus paddle stew), cochinita pibil, a grill-top taco bar with pork, skirt steak, rajas, and pollo adobado, and a mountain of fresh seafood ceviches and aguachile. Sure, there may still be a chocolate fountain and an omelet bar (and warning: there's a payaso on premises for the little guys) , but five-dollar margaritas and live mariachi more than make up for those more ordinary brunch inclusions. Come check out some of the dishes being served at Frida's Sunday brunch, one of the best Mexican buffets we're yet to find in L.A., in our slideshow look.
