The customer service at Neiman Marcus is top notch. Every time I visit the store I am greeted by EVERY sales associate, but not in an overbearing kind of way. And lets face it, their merchandise is not cheap. So if I am going to be making purchases I want to make sure I feel good buying my stuff! Also, the store is clean and easy to navigate.
Bonus: I love how their store has the NM Cafe. Its fun to be able to sit down after shopping and be able to have a snack (or full meal).
