If you can only go to one mall in Arizona- this is it. Catering to tourists this mall is anchored by Nordstrom, Neiman Marcus, Macy's, and Dillard's. Of course I only really need Nordstrom of those- but FYI.
The parking is a pain so I opt for the Nordstrom (blue garage) parking structure or if visiting during an off peak time the open lot near Starbucks and yard house works well. If I park in the open lot I'll enter through anthropologie right near that lot.
You can walk forever in this mall and it can be overwhelming for first time visitors.
I like the food across the street in the waterfront area better than the mall chain restaurants. I suggest lunch at Olive & Ivy and then walk to Nordstrom and get to the mall through there.
