A cool little outdoor mall filled with several quality restaurants and upscale shops. It's well designed to mostly attract the well off folks who live in the immediate area, or are staying in the nearby resorts. Having several grassy areas not only adds to the attractiveness of Biltmore Fashion Park's design, but also makes it a dog and kid friendly spot. There's actually a park feeling to it, so unlike some spots in the valley, the word "park" in the name actually makes sense.
Other than some of the restaurants, Biltmore Fashion Park isn't really a good destination place if you live far. The stores aren't really anything you can't find find at most other valley malls and shopping centers. Many of those stores also tend to close fairly early. I usually only shop at the Biltmore if I'm planning to eat there, too.
The parking situation is also a little odd. The front of the mall (uncovered) charges hourly, but can be validated. Many of the restaurants in the front also offer free valet. The parking structure located in the rear of the mall is free. In the hot Arizona summer, I'd assume it would make more sense to charge people to use the covered parking. Uncovered spots in the back of mall are also free of charge.
