One of Tucson’s best known and best loved Mexican restaurants is Casa Del Rio at 1060 S. Pantano Rd. – dishing up authentic mouthwatering Sonoran style lunch, dinner, and take out since 1979. Nothing complicated, here. Simply great Mexican food, great service, and great value. These are our commitments to you. We serve nothing precooked, frozen, microwaved or vender-prepared – everything we do is prepared and served up fresh every day. Dine in, come and get it, or have us cater your next meeting, event, or party.
