Great prices, nice selection! What more could you ask for?
This Forever 21 is located upstairs nears Barney's. It's much cleaner than the one at Arrowhead (which feels so gross and dirty, but it felt like that too when it was Mervyn's), so you feel like you want to shop at this location.
It's not as big, but sometimes it's better not to be too overwhelmed with way too much merchandise. Did I say "great prices"? (esp for Scottsdale).
