Although it is one of the older malls in the Valley, Fiesta Mall was renovated last year and really improved the experience there. Their new children's play area is very clean, large and fun, and the new flooring and decor makes it a much nicer place to shop.
The anchors and most of the stores are still the same: Sears, Robinsons-May, Dillards, Macy's. They have one of the few Disney stores left in the area and there is also a Gymboree outlet there for kids clothes. However, you can tell that Fiesta is suffering from having newer malls around. Every time I go it seems that another store has closed and a new one has not opened to take its place.
