I was hella skeptical that a Phoenix fast food Mexican joint could top a Mission taqueria. Rivas pleasantly surprised me. I chose the two burritos with chicken meal that came with rice and beans. Standard, but fulfilling rice and refried beans. The burrito was a breath of fresh grilled veggies. A warm tortilla filled with chicken, peppers and onions. So simple and yet so mouth watering. Best part was that the burrito was so big that I got to save the second one for my flight back to SF. Oh, and this whole package was under $7.
