Not the best UO I've been too, but definitely a good sized one. If I went to school as ASU, I would be in love with Mills Ave, as there are cute shops all along the street.
This UO is just the same as any other, decent home selection, clothing, selection, as well as shoes selection. The thing this store lacks is customer service as no one greeted me the entire time I was in the store, which was an entire 30 minutes. After the first 15 I just give up when no one acknowledges me and my spending power!
