Okay, so I have a little bit of bias towards Nordstrom. I freaking love Nordstrom!
The store is always clean, and the staff are always friendly. I have never had such good service anywhere else. I especially love that Nordstrom will return or exchange an item with no questions asked.
Aside from the service, the selection is very nice. I always go during the half yearly sale, so that I can get some good deals on my designer duds!
I am big on shoes and the selection is very good. They always have some cool shoes that I can't seem to live without. Also, the staff in the shoe department are very good on helping to make suggestions when I am not sure what I want.
If you go, go in June or January when the sales are great! Make sure you check out the shoes!
