Macy's Herald Square is the stuff of legends but not necessarily for those who are serious about a quality shopping experience.
When you walk in, you're bombarded by associates trying to get you to test new scents; too many and the scents are too close to differentiate (men and women).
In the regular departments, it takes forever to get the attention of an associate, as they're short staffed for the masses of people needing assistance.
Their clearance departments especially shoes (called Last Act) are an unparalleled upheaval and chaos no one should be subject to. They have 1 (on a good day) 2 clerks taking your size request among many who have no regard for courtesy or consideration. However, the plus was an associate named Nicole who remained calm, professional and patient even with sometimes as many as 20 women asking for 2 and 3 shoes at a time.
While you may want to visit the largest store in the US, you may want to simply walk through and observe; you'll probably get better service, offerings and selections at your local Macy's.
