Situated amidst vast "parking lagoons," (to borrow the words of James H. Kunstler) the Westgate City Center is about as far away as one can get from anything "city."
In this development, one can enjoy chain restaurants, a movie or pseudo-Las Vegas monuments to capitalism (read: giant-sized billboards). However, one will surely not enjoy the randomness and sense of discovery that makes experiencing a true urban environment (i.e. San Francisco, Manhattan, etc.) so worthwhile. At Westgate, the 'city" is planned. Don't expect to wander upon a trendy boutique, art cinema or bodega. This is a Phoenix strip mall writ large.
I hate the name "city center" for this development as it leads one to expect the kind of "new urbanist" development present in Reston, Virginia, Seaside, Florida or Portland, Oregon. Those are true live-work-play destinations. They are not surrounded by "parking lagoons."
Come to Westgate for a cartoon of Disneyland or Las Vegas in metro Phoenix, but go elsewhere for a true urban experience.
