IMO Prada was one of the better outlets at The Mall. The day I was there (mid-October) there was no line and it was well organized. While a lot of the stores I saw seemed to have merchandise made for outlet stores, I don't think this was the case at Prada -- I bought a small Miu Miu wallet that I had actually seen in stores last year (and it was 100 euro!).
Compared to other stores, Prada also has a great variety of items/styles, so if you like the brand, you'll probably find something you like. read more
