The Westchester Mall is the "high" end mall of the area. The Mall has Neiman Marcus, Nordstrom's, Potery Barn, Crate & Barrel, Bose, Express, Tiffany & Co, Coach, Luis Vuitton, Burberry and other retail stores. The Mall also has a food Court and P.F. Chang's as food options. There is a Red Door Salon for pampering if that's what you're needing after some major shopping.
I'm not a big fan of the Mall due to the fact you have to pay for parking and the mall is filled with the typical "Westchester" types.
There are some stores Liz and I like. I of course love the Bose store. Liz has alot of her dress and shoe stores here so we are often shopping here on a Sunday.
