Javier Sosa opened the original Javier's in Laguna Beach in 1995 — the Aria location followed in October 2012 as the family's Vegas Strip flagship. The kitchen runs polished Mexican family-recipe cooking (the carne asada, the cochinita pibil, the family-recipe handmade tortillas) with disciplined execution above resort-chain default. Reservations run hard at peak dinner; the dining room is finished Aria-resort-polish with quieter, dinner-pacing rhythm than the property's higher-energy concepts. For Aria's most-credentialed Mexican dining room — Sosa-family pedigree carried over from the Laguna Beach original.
