Not sure why the reviews for Bloomies are so bad, I always get great customer service when I go in. On the other hand, I do not like the Galleria location. It is a bigger store, but I feel like the SAs judge you the moment you walk in. I am originally from The Bay (SF) area and lots of rich folks don't actually dress like they're rich so the SAs back home cater to everyone who walks through the door. So I'm used to dressing down when going to LV. However, here, if it looks like you're not going to buy (or can't afford it), they say hi from behind the counter and go about their merry way. Sometimes, I am left standing looking at the bags with no one to help me, and I am a VIC (just not at this store because I absolutely hate their CS).
The Neiman Marcus location is GREAT. I cannot say enough good things about them. Everyone is friendly and they greet you the moment you walk in. If there's no one there, someone will help you asap. If they are booked (which they usually are on weekends), they will apologize and tell you it will be awhile (the courtesy and acknowledgement is what I appreciate the most). For a small store, they actually have a lot of stuff. When I need to special order or reserve hard to get items, this store always seems to get it before most stores (even before the Galleria store). Courtney, Lois and Luke are the three I mostly work with. I believe Courtney is there almost everyday and she is very knowledgeable about the current line and the upcoming collections (for pre-orders). Of the three store around Tysons, if I had to go to just one, NM would be my hands down choice.
I hope that helps!
Happy birthday and happy shopping!
