They finally just opened a Rita's location in Surprise!! I think it just opened yesterday or today, but it's just as good as the one on Union Hills and 83rd Avenue.  I told my co-workers about it and we basically have been driving by during our lunch break just waiting for it to open over the past few months.
It's hard to explain the texture of the ice. It's thicker than the ice in a frozen margarita, yet it's not crunchy or unrefined like an Icee drink. Sonic has similar ice, but I feel like it's just not as good as Rita's. I guess that's why it's Italian ice. It's in its own category!

There are 3 main types: Gelati's (custard-ice-custard), Blendini's (custard-ice-custard with mix ins like Oreos, M&Ms, etc), and Mistos (ice-custard drink). You can also get just regular custard alone or flavored ice alone. One of their most famous ice flavors is Swedish Fish. There's also a sugar substitute version of their ice and today's sugar free ice flavor was Pineapple. I tried a Red Velvet Cake Gelati today with vanilla custard and it was nothing less than amazing!
The menu is a little confusing since there are so many choices. There are mainly only 2 types of custards though, vanilla and chocolate, that can be mixed with the 12 flavors of ice that consistently change. 
Before, I was solely a fan of ice cream and yogurt. Now, I am grateful that my sister-in-law dragged me here, because there is nothing quite like it yet! Now I will always compare Italian ices to this place.
