I echo PPs suggestions of Uniqlo, TopShop and Eataly.

I prefer Sprinkles and Crumbs cupcakes to Magnolia bakery. But I don't think any cupcake is worth standing in line more than 10 minutes for.

For fun looking at crazy diamonds, check out the boutiques on Park Ave.
For candy, go to Dylan's Candy Bar (across the street from Bloomingdales).
For good, quck eats, go to one of the many Europa Cafes or Cafe Metro.
For (IMO) the best cheesecake, go to Junior's (Times Square location is prob. the most convenient).
For one of my favorite restaurants in the Meat Packing District: Pastis.
For an iconic sandwich: Carnegie Deli.

Regarding credit cards at Neimans/Bergdorf: they just started taking other credit cards, which means you can finally use your debit card. I found this out when I went to our local Neiman's a few weeks ago. It's about time!
